Staff Mod 0.12.0

What's new since 0.11.0-beta.2

Staff model
- 3rd person model is 15% smaller, and is held near the center instead of the end
- 1st person model is 32% percent smaller, and is held a bit forwards, like a trident, and no longer covers half of the screen
- Add forward pointing staff model when right click is held
When right click is held, the players holds their hand and the staff where they look
Change magma block, snow block, and TNT staff
- The projectiles/explosives now spawn at the staff's tip instead of the player's eyes, making it less obstructive
- The staff user's velocity is added to the projectile's/explosive's velocity (except when flying, because Mojank)
- TNT launched by the staff no longer ignores the staff's user (will explode on impact)
