wxPython4 sequels: fix exception in connection dialog, force black text in FBD.

- wxPython4 does not have RemoveSizer in API anymore.
- On GTK3 with dark theme default text colour is white, making it unreadable.

SVGHMI: fix js exception because of trying to find already detached elements by id.

SVGHMI: better handling of page switch fade-out.

- In cases or relative jump to current page, page was keeping black after switch.
- Now keep track of undergoing page switch without comparing subscribed page to visible page.

tests: nore details, please

Github CI: upload artifact (reports) when failing

tests: add one more ignored pic to debug_project test

tests: add missing pic for debug_project sikuli test and remove depricated picture in edit_project

Github CI: use new name for test launching script

test: Fix context menu problems in debug view. This should fix debug_test as well.

- exception on right click on a wire
- tooltip hiding context menu in some case

tests: add (broken) debug_project test, fix edit_project

tests: rename build_in_docker.sh to do_test_in_docker.sh

Merge default in wxPython4 branch

SVGHMI: update generated XSLT files

SVGHMI: force initial state of Display widget to empty string.

SVGHMI: set initial displayed value of input widget to empty string.

SVGHMI: add warning_labels, same as optional_labels but emits warnings at build time if element is missing.

SVGHMI: update generated XSLT files

SVGHMI: generalize detach/re-attach of binary choices for ToggleButton, PushButton, Button and Keypad's Shit and CapsLock.

SVGHMI: also use order-preserving detach re-attach for hiding and showing active and inactive state.

SVGHMI: fix Switch widget so that order of choices elements is preserved across detaching and re-attaching.

SVGHMI: update generated xslt files

SVGHMI: nasty scope shadowing bug... was making funny recursion, leading to really slow interaction.

SVGHMI: fading page switch : to avoid blinking, page stays black once fading finished and next page is still not ready.

SVGHMI: fading page switch : defer update of classList to next animate() call when finishing transition.

classList update was happening in the same call as switch_page(), but this call is not meant to do any change in the DOM. This was triggering unwanted style and layout recomputation.

SVGHMI: rework Switch widget : detach/attach elements instead of hiding with style.display, detach all possible choices at init.

SVGHMI: add fading transition to make page switch feel more responsive on slow machines.

SVGHMI: add a way for widgets and other yslt2 files to add css definitions to resultng page.

SVGHMI: update generated XSLT filesw

SVGHMI: XY graph build produces error message if provided curve_N are not consistent.

SVHMI: Keyboard: Replace untouched value when typing directly after open. Make info string (HMI variable name) optional.

merged

SVGHMI: update generated xslt.

SVGHMI: Add support for fixed X range (duration) on XY garph.

SVGHMI: add widget update rate limit on variable change.

SVGHMI: fix parsing of floating point and negative min and max limits in widget label syntax.

Fix typos breaking IDE

Added preliminary CLI. Supports building a project, transfering and running on PLC.

IDE: fix exception happening in debug mode when logging process termination.

SVGHMI: Adapt to Inkscape 0.92 "-e" replaced by "-o" in 1.2, and workaround access right problem when generating thumbnails.

Various fixes to make svghmi_traffic_light example bahave on windows.

IDE: fix saveAs dialog

IDE: fix permission checking on windows for IDE project directory.

SVGHMI: fix active/inactive being swapped in ToggleButton

IDE/Windows: Find Inkscape binary even if Inkscape was installed for current user only.

IDE: Workaround exception caused by dead C/C++ swig-wrapped object when debug still try to update view after close.

IDE: better permission checking when opening a project.

Merge changes from default to wxPython4 branch

SVGHMI: more fixes for XY graph + add XY graph test.

SVGHMI: Seems inkscape doesn't necessarily use tspan inside of text anymore.

SVGHMI: multiple fixes in XY graph widget. WIP.

SVGHMI: fix dropdown widget in case it is used as language selection widget

global i18n definitions changed but widget wasn't updated accordingly.

SVGHMI: prevent exception with date/time formating in sprintf.js if lang wasn't already set.

SVGHMI: Add forEach to local copy of pythonic.js

SVGHMI: many fixes on xy trend graph. WIP.

IDE: fix exception happening in debug mode when logging process termination.

SVGHMI: fix syntax problems in xygraph

SVGHMI: fix widget's update frequency forcing : syntax checking was enforcing unit and js code was using undefined variables

SVGHMI: fix syntax error in sprintf.js and force makefile to regen xslt files when sprintf.js changes

SVGHMI: fix test/projects/svghmi "unspecified" frequency that was actualy specified...

SVGHMI: Add premature implementation of XY chart.

merge default

Tests: No need to archive test results before uploading them as action artifacts.

Tests: ...

Tests: re-enable running test in github action, now that docker image should be cached.

Tests: temporary disable problematic part, to force action to succeed so caching can happen.

Tests: give test directory when creating container, not when running test.

Tests: fix docker image export for GitHub Action caching.

Tests: More fixes amd enhancments to run tests on Github Actions

Tests: use script rather than alias so that bash doesn't need to be interactive shell with a TTY

Tests: remove -it from docker invocation

Workaround "The input device is not a TTY" error on Github Action.

Create run_tests_in_docker.yml

SVGHMI: Add support for forcing widget update frequency with period longer than a second. As an example, "HMI:Display|10s@/myvar" updates variable every 10 seconds.

SVGHMI: cosmetic fixes + removed dead code

SVGHMI: allow widgets to disable clipping on variables given with min and max. Setting this.clip = false disables clipping.

SVGHMI: allow designating widget's sub-elements as main element child rather than descendant. Names staring with "/" in yslt call to labels() only match direct widget childs.

SVGHMI: add localized Date and Time support to sprintf.js. Use with "%D" or "%2.1D" format style.

Minor changes to README.md

wxPython4 sequels: usual naming problem in grid cell change events, non kw-args to menu.Append and event not being skipped.

Tests: Fix missing <br/> in generated html report.

Tests: add HTML report generation and a workaround to bad exception handling in sikuli.

In case of exception in python code, and since a thread is running
to observe stdout, sikuli was never terminated after an exception.
Unfortunately sys.exepthook doesn't work in that version of jython/sikuli.
Test are now written inside functions witch are passed to run_test to deal
with exception.

Tests: refactored sikuli based test

IDE: Postpone execution of keyboard shortcut commands when given while previous command is still being executed, to prevent CTR/builder jamming.

IDE: in case of unhandled exception, write bug report to given log file, so that test report can have it.

Merged default's changes in wxPython4 branch

Tests: fix project edit test sikuli IDE test.

Background click based on bitmap matching doesn't work.
Grid dots are not good match candidates.
Rendering probably affected by virtual display's bpp or rasterizer approximations.
