Added MyCursorAdapter from an attempt to accelerate application loading performance, currently unused.
Used Cursor Loaders for better loading performance, main thread better but compose new message still laggy.
Updated Android Manifest with correct names for several activities and added adjustResize for screen adjusting on keyboard up (still not working).
Removed unused properties from .gitignore.
Refactored some functions (like RegisterReceivers) for better code readability.
