Very simple chat control plugin.
By very simple I mean very simple.

Commands
/mutechat - mutes that chat
/unmutechat - unmutes the chat
/clearchat - clears the chat

Aliases
/mutechat - /mc
/unmutechat - /umc
/clearchat - /cc

Permissions
/mutechat - cerq.chatcontrol.mutechat
/unumutechat - cerq.chatcontrol.unmutechat
/clearchat - cerq.chatcontrol.clearchat

Yes, I know this is very basic. I am just experimenting.
