Updated to current version
Fixed Movement Issues for Blobby

We weren't initializing the xvel and yvel to 0 on blobby's creation so
they would still have whatever values the previous blobby had on his
destruction.
Updated Blobby Image
Modified Makefile to work on Windows and Mac
Updated git ignore to disregard .o files

Also tweaked makefile
pulled from Sam's branch. Removed the Ground.bmp Image from levelmanager.
