Allow ctcp replies through floodcount after ctcp'ing a large group.

Browse source 
A large group is any $$ or $# or a channel with more than
floodcount/2 local members, checked on each server separately.
Note that floodcount checks are done on the sender's server.

The special treatment is active for 15 seconds.
