Basic Side and Head collisions working

-The player now interacts basically as it should for rectangular
platforms.
-Head collision is simple at the moment, there is a note in the code
under jack.cpp collide response function
-Fixed a few small errors as well.
-Adjustment to values and such will be made later when we finished more
of the base code and move on to deciding dimensions and specifics.
-I may mess with how platforms are shown to the window in main. However
i may refrain from doing that until after the conversion to SDL 2.0
