Added Mass Channel Modes

Mass channel modes now assume a MODESPL=4 and just crank out each line
individually.

WARNING: **YOU MUST SET FLOOD CONTROL TO A REASONABLE RATE IN ORDER TO
AVOID BEING FLOODED OFF THE NETWORK! I AM NOT RESPONSIBLE FOR THOSE WHO
DO NOT SET FLOOD COMMAND TO QUEUE OP COMMANDS AND GET DISCONNECTED FOR
EXCESS FLOOD!**
