Made a admin command for refreshing class data on one or more players.

Updated infect module to use new reload function.
Fixed typo in command description.
Known issue: Models isn't always restored on zr_human. If "default" is used, there's practically no model change. Possible solution: Store path in a buffer when the player join a team and select a model. Then read from that buffer when "default" is used.
