Added a tick system for making sure movement speed is the same across platforms and a fps meter.

This tick system needs to be reworked because it currently limits player movement to one pixel per frame at maximum.
It can handle very low movement speeds though.
Again, updated to reflect changes
Updated goals list slightly
Revamped movement system and started working on collision
Changing drawing method to only rerendering map at map updates
Huge performance increase

Made map rendering load to a surface file when it changed and then paint
that every frame instead of rendering all the tiles separately every
frame
Updated installation instructions
Updated checklists
