chanserv: SET TOPICLOCK and KEEPTOPIC (topic subsystem)

Browse source 
Adds topic tracking: a TopicChange event (parsed from InspIRCd FTOPIC, our own
changes filtered by SID like FMODE) and a stored topic on the channel, folded
through the event log. TOPICLOCK reverts a topic change by a user without
op-level access back to the stored topic; KEEPTOPIC remembers the topic and
restores it when a registered channel is recreated. Both via the typed
ChanSettings path; shown in INFO. Parse + engine tests cover both.
