* winner. The side with the higher timestamp loses, from this point on we
* will call this side the loser or losing side. This should be familiar to
* anyone who's dealt with dreamforge or TS6 before.
*
* When two sides of a split heal and this occurs, the following things
* will happen:
*
* If the timestamps are exactly equal, both sides merge their privilages
* and users, as in InspIRCd 1.0 and ircd2.8. The channels have not been
* re-created during a split, this is safe to do.
*
* If the timestamps are NOT equal, the losing side removes all of its
* modes from the channel, before introducing new users into the channel
* which are listed in the FJOIN command's parameters. The losing side then
* LOWERS its timestamp value of the channel to match that of the winning
* side, and the modes of the users of the winning side are merged in with
* the losing side.
*
* The winning side on the other hand will ignore all user modes from the
* losing side, so only its own modes get applied. Life is simple for those
* who succeed at internets. :-)
*
* Syntax:
* :<sid> FJOIN <chan> <TS> <modes> :[[modes,]<uuid> [[modes,]<uuid> ... ]]
* The last parameter is a list consisting of zero or more (modelist, uuid)
* pairs (permanent channels may have zero users). The mode list for each
* user is a concatenation of the mode letters the user has on the channel
* (e.g.: "ov" if the user is opped and voiced). The order of the mode letters
* are not important but if a server ecounters an unknown mode letter, it will
* drop the link to avoid desync.
*
* InspIRCd 2.0 and older required a comma before the uuid even if the user
* had no prefix modes on the channel, InspIRCd 2.2 and later does not require
* a comma in this case anymore.
