Made tiles 16x16 , implemented basic physics
Fixed gravity somewhat, accidentally broke collision detection
Added console, fixed collision detection and physics…kind of

Collision detection and gravity/jump physics still need work
Cleaned up, added TODO
Huge refactoring of code

- split classes into separate files
- added MakeFile
- cleaned up most of the code to my style
- switched to C++11
- switched to vector instead of array for Tiles
- !!!!broke graphics somehow
- !!!!broke font somehow
