* Removed unnecessary case sensitivity in meetme list, lock, unlock, mute,
unmute, and kick commands.

* Separated meetme lock/unlock, mute/unmute, and kick commands into their
own registered commands to simplify tab completion and parameter checking.
meetme_lock_cmd(), meetme_mute_cmd(), and meetme_kick_cmd()

* Simplified meetme_show_cmd()
