[IRCServices Coding] SET RESTRICTED, and possibly AKICK flaw

[Bergee]

	Indeed, I recall the channel that this happened on having no bans at
all.  Or well, the IRC server didn't think there were any...
	I'd also like to throw a note that it would be highly annoying to have
Services up and remove all extended bans that user's place.  I think
it's something that can pretty much be accepted that if one installs a
module that adds an extended ban -- it simply won't work with Services.
 I'd rather see support for the built in extended bans and simply ignore
other extended bans.  Or perhaps only do that when a configuration
option is set to ignore them so that an administrator must understand
the ramifications of doing so.  And if that isn't set, remove unknown
extended bans.  I don't feel like this is a "good solution" but I feel
like outright removing support for extended bans is a far worse one.
