SVGHMI: Fixes UI lifecycle problems

Was sometime showing HMI tree of previously closed project : no more module globals to store hmi tree.
C++ dead object exceptions happened when re-opening SVGHMI UI or building after close of UI.
// widget_textlist.ysl2
widget_desc("TextList") {
longdesc
||
TextList widget is a svg:group, list items are labeled elements
in that group.
To use a TextList, clone (svg:use) one of the items inside the widget
that expects a TextList.
In this list, (translated) text content is what matters. Nevertheless
text style of the cloned item will be applied in client widget.
||
shortdesc > A named list of ordered texts
arg name="listname"
}
widget_defs("TextList") {
| texts: [
foreach "func:refered_elements($hmi_element/*[@inkscape:label])[self::svg:text]" {
| id("«@id»"),
}
// could find a proper way in xpath to reverse()
| ].reverse(),
}
widget_class("TextList");
