Warlock Pre-Pull Clickable Reminders

Pre-pull reminders for warlocks.  Works with DBM, BigWigs, and Raid Warning pull timers.  The buttons are clickable!

Currently has buttons for the following:
- Demonic Circle: Summon (triggered at 10 seconds if out of range or does not exist)
- Rank 1 Life Tap (triggered at 8 seconds)
- Potion of Speed (triggered at 5 seconds if in inventory)
- Potion of Wild Magic (triggered at 5 seconds if in inventory)
- Destruction Potion (triggered at 5 seconds if in inventory)

Potion buttons will go away if you enter combat prematurely to prevent accidentally using your 1 potion.
