Allow raid assistants to initiate ready checks by typing "rc", restoring functionality removed in patch 3.3.

This is a lightweight, one-time addon designed to fix a specific bug introduced in patch 3.3.0. (Raid Assistants are unable to perform ready checks.) This addon will be phased out once the bug is fixed, presumably in 3.3.1.

Only the raid leader needs to be using this addon. Other people can have it running as well but it's not required.

Raid assistants can trigger a ready check by typing (case-insensitive, spaces between words optional):

"rc" by itself
"ready check" anywhere in the message. e.g.: "Can we get a ready check, please?" (Yes. Yes, you can.)
Exception: not "ready check assist[ant]". This should prevent bogus ready checks after someone asks "What addon is that?"

The channel doesn't matter. Whispers, raid, raid warning, yell, etc., all work.

There are a couple slash commands available as well:

/rca <on|off> - quick way to enable/disable the addon
/rca advert - tell all raid assistants that you are running this addon

Feedback welcome!
