Filter list of console commands allowed in the main channel

[WizardCM]

I had this idea a moment ago.
Add a config option to allow certain, 'custom' commands that anyone can run in the main (#minecraft) channel.

An example might be something like !list or !players (which would be /list and /players if done ingame) which would use, in this case, Multiverse (to list who is in each world) or RoyalCommands (to show who is afk) to list the players, instead of the command built into BukkitIRCd (which just lists the players that have joined the channel).

Other possible examples of this may be something like !lag or !mem to show memory usage to anyone who wants to check if the server's lagging, or to just see if the server console is keeping up.

The layout of this config option would be identical to the kick-commands one (so, without the !).
