Fixed mid-air freezing

Basically removed the dependency of the updating method in Game1.cs on
the KeyboardState.
Still need to clean up further. Also need to fix the Facing Forward
mechanism; and Jump animation needs to stay while in the air, even when
keys are not pressed.
Just a bunch of random files

that somehow got changed.
Again, caused by rebuilding the files.
