[IRCServices] New UnrealIRCd channel modes (+I and +j) - not recognised by Services

[Andrew Church]

>The next UnrealIRCd version (3.2.3) will feature two new channel modes: +I
>(invex) and +j (join throttling). They're already in CVS, for those interested.
>However, it seems that Services doesn't support them.

     Given that they're not even in an official Unreal release yet, this
shouldn't be surprising...

     I'll look into adding support for the next release.
