SVGHMI: Fix bug introduced when merging default

SVGHMI: Add use of Python PLC Globals it test

SVGHMI: add "unsubscribable" property to widgets in order to generalize what already happens for jump buttons.
In most cases jump buttons do not really subscribe to pointed HMI variable, path is given as a relative page jump path. When widget.unsubscribable is set to true, no subscription is made on page switch, but still offset is updated.
This fixes bug happening on relative jump buttons without "disabled" element where offset did not change on relative page switch.

SVGHMI: Added widget toggleButton.

SVGHMI: Changed widget button handler to element attribute.

Runtime: create .md5 file at the end of all transfered files being written to disk, so that it presence indicates completeness of transfer.

IDE: Main toolbar : Show repair button also in stop mode. Move repair button after disconnect button.

Runtime: fsync() files when transfering them, to prebent data loss when poweroff soon after programming. Fixed variable naming as a side effect.

PLCObject : reorganize code in StartPLC(), add a PreStartPLC() empty method, to be overloaded by runtime extensions.

Solve import order problem when POULibrary imports ConfigTreeNode because of UserAddressedException. Now UserAddressedException is declared in POULibrary.py, as a quick and dirty fix, but some independant module should be created for beremiz exceptions in general.

SVGHMI: stop using eval in change_hmi_value, apparently slowly leaking memory.

SVGHMI: Switch widget was picking sub-elements from original SVG, not the result SVG ehwe clones are unlinked, thus making problems with svg:use based widgets.

SVGHMI: When unlinking a clone of a group, do not create additional group, but merge transformation and styles, and replace label. This allows svg:use based widgets to directly access elements of svg:use targeted element.

SVGHMI: Applies clone unlinking to widget themselves, not only to clones inside widgets.

SVGHMI: Makes error when HMI tree is not well formed. Prevents multiple and non-first HMI_NODE, and ensure that all paths in HMI tree are unique.

Added FatalError call to Libraries code gen, so that they can emit messages addressed like config tree nodes do.

SVGHMI: more Widget properties declared ES6 style.

SVGHMI: Switch widget now use class declaration

SVGHMI: Update Button widget to class declaration, and add a button widget in tests/svghmi.

SVGHMI: explicit handling of undefined maximum widget update frequency

SVGHMI: removed dead code

SVGHMI: Back button updated to class style

DEBUG: (IDE side) fixed wrong implementation of anti-rapid-fire leading to systematic delay in subscribing

SVGHMI: Exclude non-widget HMI:* labeled elements from hmi_widget. Namely : HMI:Page HMI:Lang and HMI:List have been excluded.

SVGHMI: clean up dead code, update generated xslt.

SVGHMI: apply per class overloading of sub/unsub to Jump widget

SVGHMI: apply per class overloading of sub/unsub to ForEach widget

SVGHMI: Widget's specific sub/unsub traits are now wxpressed in widget's class.

SVGHMI: Parameters common to all widget constructors now passed as ordered parameters.

SVGHMI: One class per widget type, widget objects are instances of these classes, and members are passed through constructor. This allows to keep compatible with previous widget_defs template used in most widgets.

SVGHMI: Add an exslt function to collect used widget types, in order to only include necessary JS definitions in furure changes.

SVGHMI: Systematically output local name as /* comment */ when emiting content.

Merge

SVGHMI: Fix flawed logic to place nodes in the HMI tree, leading to wrecked tree in some cases.

Added button and circular bar widgets.

SVGHMI: added more meaningful namespaces to emit javascript code from.

SVGHMI: moved JS code of foreach and jump widget in corresponding widget_*.ysl2. To be continued.

SVGHMI: spread JS code from svghmi/scripts.ysl2 in other .ysl2 files, using dedicated preamble and epilogue namespaces

SVGHMI: Introduced "emit" to simplify producing per-topic code and content from anywhere in code. Applied to debug output, next to JS.

SVGHMI: Move reflective debug tags from "reflect" to "debug" namespace, preparing for per-purpose namespaces.

SVGHMI: Added scripts.ysl2

SVGHMI: moving code wher it belongs, and reformulate some declarations for better readability.

SVGHMI: HMI:DropDown: more documentation.

SVGHMI: Comments in HMI:DropDown source code

SVGHMI: HMI:DropDown menu aligns to selected when opening

SVGHMI: When clicking outside of opened HMI:DropDown box, close it.

SVGHMI: Fix HMI:DropDown flicker on close.

SVGHMI: HMI:DropDown now temporarily takes content from widget's arguments, until HMI:List is implemented.

SVGHMI: Connect HMI:DropDown to value in HMI Tree, in svghmi test as well.

SVGHMI: fix probable problem in HMI:Input, where value could be applied to wrong index if used in relative page.

SVGHMI: HMI:DropDown element is brought in front when opened, so that it isn't occulted by other widgets at the same level.

SVGHMI: HMI:DropDown now catches all clicks when open

SVGHMI: Add button element to HMI:DropDown, also fix problem with computed box margins.

SVGHMI: HMI:DropDown now scrolls forward and backward

SVGHMI: progress on HMI:DropDown - now selects some value on click, and close

SVGHMI: HMI:DropDown work in progress, intermediate commit. Now menu's rectangle grows up to viewport borders.

SVGHMI: intermediate commit while working on dropdown widget.

Here is the plan :
HMI:DropDown : svg:g of svg:rect + svg:text
rect is extended to match content size, and if content size exceed page size, user can scroll
HMI:List : either HMI:List:ListName as svg:text, one tspan per list entry
or HMI:List:ListName:Foreach:HMI_CLASS:SUB/PATH/TO/VALUE@/ROOT/PATH as empty svg:g
