Jump, Crouch are not Hooked

[pnill]

Need to hook the Jump, Crouch, Fire (Release, Hold, and Fire) functions so that we're able to send that data in the player snapshots to the server.

Fire is now hooked. It was decided that jumping probably doesn't need to be handled... Now just need to handle crouching.

Jumping may need to be handled after all, as it seems when a dummy player picks up boots and jumps the game appears to think they're falling and applies fall damage on the server side but the client never sees this damage.
