Added online color selection; now using newer patrick head

Added color selection to online mode from netLobby.
Color was added to the netLobby update message and to the player joined messages. Players are recolored when the game starts #20.

Replaced lil_patrick with PatrickOverPatrick -- a Patrick head over lil_patrick just like BradOverPatrick.  Because the lil_patrick head is part of the skeleton somehow.  Removed the if("lil_patrick") checks from the code. 

Looked at HeadHandler but these heads aren't bone-ed so that script doesn't really apply.  Heads are only attached to the head joint however so switching isn't difficult.  But the lil_patrick base may need some work to allow different heads. #192 @ChrAfonso #221
