[Patch] Improved Spell Reflection - multitarget reflecting

[Auntie Mangos]

MaNGOS Rev. 10154

Bug report: http://getmangos.eu/community/viewtopic.php?id=13329&highlight=improved+spell+reflection

What does it fix?

This patch adds the multitarget reflecting effect for Improved Spell Reflection talent. It chooses only party members, the number of them depends on the talent's rank. Party members are sorted in their distance from the caster's order and the aura applies to the closest ones.

It also applies removing the rest of spell refl. auras after reflecting, because this multitarget spell reflection applies to only one spell cast at any protected party member.

Radius is set to 20.0 yards as it is said in the talent's tooltip. There is no such data in the dbc so I've written it this way.

I tested it with 6xWoW running :cool: and it worked well.

Please test and comment
