M16, M4, and M2HB loading animation

[Griffon2-6]

The current M16 and M4 loading animation is unrealistic, according to the loading animation in America's Army. In America's Army, which is developed by the US Army, The magazine is inserted and locked into place, then the bolt is pushed in. That slide is never pulled unless you're trying to unjam the gun, in which case a cartridge would be emptied from the gun. Also, the heavy weapons do not have a loading animation. One should be added if possible, I know there are no hands shown when attached to a heavy weapon.

The slide is only pulled if the previous mag was expended. Seeing as BF2 can only have one reloading animation - you can't have both. But its a nice touch in games like AA, CoD2 etc.
