Build 26494321

The heavy, teardrop, uppercut, cobra, and double-end bags in every gym now have enhanced physics.
They swing, spin and rebound off how hard and where you hit them.

New: physical punching bags
Every bag now reacts to the actual force and angle of your punch.
The new bags are in Engine Room, USA Boxing, the JP gym and the multiplayer gyms. Bag heights and chains match the gyms they hang in.

Multiplayer
Everyone hears your punches. Bag hits are now heard by every player in the gym, not just the one throwing them.
No more frozen bags. When someone other than the host punched a bag, it could freeze for 5-10 seconds for everyone else. It now responds almost instantly.
Bags swing the same in multiplayer. A single punch could count up to three times, so bags swung about 2.5 times too far. One punch now lands once, same as single player.

Fixes
Fixed the grayscale effect greying out materials it was never meant to touch.
Various stability fixes from cleaning up our build branches.
