Added 100 new puzzles to Monochrome [15x15].
Removed lesser-used features and cleaned up the UI:
- Removed the HELP usage count display.
- Fixed drag-related settings to default and removed them from the Options menu.
- Moved visual appearance settings so they can now be changed directly in-game.
- Standardized the in-game font.
- Restricted screen size options to 860x720 and Fullscreen.
