Merge latest changes from default

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

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

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.
