Now able to Switch between different Scene collections.
All Scene ".Xconfig" files now stored in the "sceneCollection" folder.
Changed "GetApplicationName()" added "Profile: SceneCollection: " to the beginning of the app name.
Added "Scene Collection" Combo Box in Settings General
Can add/rename/remove new scenes collections in settings general.
Can add/rename/remove new scene collections while streaming.
Can change scenes Collections while streaming.
This enforces the warning that settings will not be applied until
streaming is restarted from the settings dialog for all profile settings
Also fixes a bug that would prevent start streaming/recording buttons
from being properly enabled/disabled when switching from a
recording/streaming only profile to a streaming/recording only profile
on stream stop
Additionally, the microphone volume meter got disabled when switching
from a profile with microphone enabled to a profile with microphone
disabled while the microphone was still active
Make the Profiles dropdown have focus instead, so accidental keypresses
don't change the current language. Also make cancel cancel the language
setting and make user confirm changing it when switching settings pages.
