Scripts/Ulduar: Spellscripts for Mimiron

Cutting the commit in pieces, so that the diff can be viewed on github...
in this commit i have not included the hacks in spellmgr.cpp. the problem is that current implementation of auras will not allow caster to track this target if the spell is not active on caster itself (joschiwald and I discussed this a lot). the spell also hits the MKII. so in spellmgr.cpp eff0 is hacked to hit both caster and DB target, thus we need this to finish the hack.
