Freeze Everyone at Course Vote / Room Join [XeR]

NOTE: Outdated by kinopikovh's version

FC will be all zero's thus allowing the following events:
If you join an open room, you freeze everyone except you.
If you host an open room, whoever joins you, they freeze. Nothing happens to you.
If equipped with a button activator, when you join a WW then activate the code, you freeze the entire WW (except you) at the Course Vote.

X Values:

3F800000 = Default
41100000 = Essentially a Matrix/Lag code. Character spins in a crazy fashion after selection. Exhaust gases, sparks, etc are so huge, they lag the game. Online: Untested, may just cause you to get disconnected.
