* 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
* Add a log when auto stopping stream / record
I had a hard time deciphering why the stream stopped automatically for someone when using the plugin as the logs contained nothing indicating an error or an action from the plugin.
He activated the checkbox to auto stop stream when a scene is activated (which I didn't know) so the plugin was doing exactly what asked.
I think adding a log is a good idea for an action as important as stopping the stream.
I added the same for starting stream for the same reasons.
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)
