working on the snake: added updates, turning, and movement.
I have an idea for how to draw it. Checking this in in case it doesn't work out.
Merge branch 'master' of https://github.com/mynameismiek/SnackySnake
moved GetCorrectedBoundingBox to its own static class. Added more collision checking for the snake. IT LIVES! The snake moves and it's parts rotate... need to add input handling to make sure its all OK.
