[mr2685] Fix typo in Mutated Plague spell handling
[mr2686] make buff/debuff different by spell aura SPELL_AURA_MOD_MECHANIC_DAMAGE_TAKEN_PERCENT

Should fix Plague Sickness 70953 that this is an negativ aura (debuff).
[mr2687] make DoSummonWild a little bit better
[mr2688] Some Ulduar target limitations
[mr2689] Add some custom spell radius for ICC + some other spell related stuff from ICC spells. My aim is to remove all unnecessary hacks in "Spell::FillCustomTargetMap(...)", but thats needs livetests (at first on my server).
Thats a preparation for this "spell hack remove"
[mr2690] Cleanup in Bone Spike Graveyard
