nickserv: grouped nicks (GROUP/GLIST/UNGROUP) and GHOST

Browse source 
A nick can be grouped to an account and then identifies to it; the store
resolves an alias to its account everywhere it authenticates. GHOST (and
RECOVER) rename off a session using a nick you own. Grouped nicks
federate and are dropped with their account.
