v0.2 update

Main changes in this version:

• settings page moved so it doesn't get overwritten by large games (was the case with sokobuino). Breaks compatibility with the previous version so you really should update.
• super easy installation of the library and board, just copy and paste the folders in your sketchbook
• more examples about physics, collisions and stuff
• ability to use different fonts at the same time
• Improved, more stable bootloader
• Faster Bitmaps
• new INVERT color
• pixel wise bitmap detection collision
• many minor improvements and bug fixes

See changelog for more details.
