* move addSelectionEntry to AdvSceneSwitcher class and allow select entry to be 'selectable'
Can be useful for implementing 'current transition' as an option or just allowing to select 'None' for screen region ignore
* Add option to select 'current transition'
* use GetWeakSourceName() where possible
* add getCurrentScene() to scene group
* silence OBS warning log and fix typo in audio switch
* extract showing initial status of widgets to function in generic switch
* adapt UI for i18n
* add placeWidgets() helper function to ease translation
* add hint about Transition Matrix plugin on Transition tab
* translate
* rework UI of file tab
* write status of plugin to scene info file
A deadlock could occur if the save callback is called just before the frontend set functions are used.
Thus unlock() is necessary before setting current scene or transition.
(e.g. if start recording is activated just before using the above functions, as this apparently triggers a save() call)
