Subject: -Ensure .tscn and .tres always save in a deterministic way, fixes
 #2495 -Scene edit state is saved outside the scene now, to avoid changes
 .tscn files when nothing really changed -Created a VariantWriter helper to
 unify all variant to text writing -Moved SceneFormatText writing to
 VariantWriter -Moved ConfigFile to use VariantWriter and VariantParser, added
 compatibility mode for old .cfg files that use engine.cfg format
