Smarter slash command lists.

Whisper and chat slash command lists now auto-fill themselves with all
possible aliases.  So if you put /tell in your whisper commands list, GP
will be smart enough to also add /minecraft:tell (and similarly for
plugins, including all aliases registered via plugin.yml for those
commands by those plugins).
