[Request] Internal Cooldowns for item/enchant procs
 

i added the internal cds for the Power Torrent enchant and the DMC: Volcane procs to the cooldown engine, would propably be very usefull for other users too if this and a lot more other procs internal cooldowns could be tracked through the cooldown-engine.

theese two seem to work as expected for me.

also, a way to track item-cooldowns without the need to register them would be very usefull. adding one line to the script when you get some new onuse-item you want to track is not that much work, but still... the information is available through the game-engine, so it should be possible to track them without the register stuff.

Add into RDX.

It is complicated to get the item cooldown. For the moment, it is the easier way I found.
