Channel Cancel checks for Channeled AOE DPS Spells

Hello everyone,

I liked the channel cancel I did on mage recently, where they cancel blizzard if there is only 1 enemy left. I decided to do the same for the following classes:

Druid: Hurricane
Hunter: Volley
Priest: Mind Sear
Warlock: Rain of Fire

I moved the "ChannelCancel" action to it's own file, so other classes could benefit from it. I removed it from the mageactions.
