OperServ: SNLINE realname bans

Browse source 
SNLINE ADD [+expiry] <realname-regex> <reason> / DEL / LIST — a realname
R-line the ircd matches against connecting users' realnames. It's just
another kind ("R") in the generalized X-line handler: same event-sourced
list, lazy expiry, and burst re-assertion as AKILL/SQLINE, keyed by
(kind, mask). The mask is kept verbatim (a single-token regex; use . or
\\s for spaces) and an all-wildcard pattern is refused. STATS now counts
it too.
