Ready Check, Pull Timer

Adding a Rapid mode for pull timer automation.

Type /rcpt rapid to enter into a timer-first, ready check-second workflow that keeps your raid group pulling in a timely fashion.

Rapid mode automatically enqueues a new timer when combat ends, and can be deferred manually (if you need a second to discuss something... or kick your lowest DPS) or automatically if the ready check is not successful with some margin before the pull.

-- BONUS: Actually implemented the new options controls
