Added the Grenade Cartridge to the armed player

Added the Grenade Cartridge to the armed player
Removed all of the old models and added in the models that are going to be used for our game.
Added in all the models for the game.

All the models have been added to the frame work. I also changed the
name of some files as they had typos (those are the files that may have
appeared to have been deleted and then added back).
Merge remote-tracking branch 'origin/Wes'
Coded grenade classes.

I added the code to the grenade classes to give the affect that I
wanted, that is it damages enemies and it pushes them away. Should still
add code to the grenade that makes it look a little more like a grenade
and so that has an explosion sound.
Added in new sounds for the game and added the grenade affects.
Bitmap Additions and implementations
Fixed it so space does not shoot and jump at the same time.
