opercmds: refactor checkban to use IRCParser, and implement --channel

Browse Source 
--channel is really just a wrapper around the $and and $channel exttargets, but it exists separately for convenience. Closes #491.

CHECKBAN provides a ban checker command based on nick!user@host masks, user@host masks, and
PyLink extended targets.
If a target nick or hostmask is given, return whether the given banmask will match it.
Otherwise, returns a list of connected users that would be affected by such a ban, up to 50
results.
If the --channel argument is given without a target mask, the returned results will only
include users in the given channel."""
