Updated ver. for Warlords of Draenor

Ver. is now 60000
Fixed Divide By Zero bug on load

Additional checks now needed in DKIRunes_BarUpdate (for some unknown
reason, since it technically should have happened in earlier expansions
as well)
Fixes for 6.0.2

+Death Knights no longer apply scarlet fever, physical vulnerability, or
weakened blows, so all the code that checked for such things is now
gone.
+ frost fever spell id changed
