Ouya controller mapping for desktop

Keycodes change when connecting an Ouya controller to Windows neko and cpp (can't check mac).
Added debugDraw for Hitbox (only triggered if they're in a Masklist) + fixed calc of parent Entity Mask hitbox (partially addresses #241)
Fixes for masklist collisions and debug drawing:
- Added project() to Hitbox (now handling offsets)
- Added min/max corrds to Polygon
- Masklist updated to differentiate between Hitbox and Polygon (to handle bounds correctly)
