- added dk battle rezz
- added jps.useBagItem(itemName) , use like jps.useTrinket(..), for pots/flask/landshark...
- moved all ground blicks to jps parse :)
- frost mage update (maybe here is a little DPS update needed)
- arcane mage update 5.3 (should be nice, have to less gear to check DPS)
- added findTanksInRaid (return all Tank units, not just one like findMeATank)
- holy paladin 5.3 & stop Casting support, maybe we should move this to a central file after testing more)
- lot of bugfixes
