ThatFMC - Unnamed camp game Ver 0.1.9

- Bugfix: white background image in notifications.
- Added experience system
- Added leveling system
- Added leveling menu.
- Characters ready to level have a * in their name

- Change: Background images from reward now keep their normal aspect with a black background. I need to improve that even more and expand, but the solution is temporary.
