Engine started

All the most basic stuff is done: input and movement and collision.
Most of this stuff was nearly included in the Flixel library so the job was quite "easy" and "fast" and "free of mind-breaking never-before seen errors". But, as everything I did before was with C++/SDL, this surely was a big step forward...)

Presenting leafboy as the first playable character! :DD (fuck yeah, breakthrough imagination)

Arrows to move. Nothing more yet.


NEXT STEP:
- map loading
- gravity-jumping system.

NEXT NEXT STEPS:
- adding menu
- enable to change between maps (there will be no levels nor scrolling, just different static 480x320 maps)
