Add support for Kingmaker ally rarity mod

[Blitz54]

Description of the problem being solved:

EDIT: Needs work. Reasons below.

If this is still true, then a few things need to be fixed. Necromantic Aegis currently applies INC rarity to the minion from a shield, like Wheel of the Stormsail.
Animated Guardian also should not gain rarity from his gear. PoB currently let's AG gain rarity.
Still unsure if Kingmaker Aura should give minions rarity or not. Can't find an answer about auras giving rarity.

Kingmaker give allies 30% inc rarity. Implemented now

Steps taken to verify a working solution:

• Equipped Kingmaker and made sure rarity for player does not increase, but minion does.
• Imported a support build into the party and the player correctly gets the rarity, along with the minions.

Example on how you could filter out IIQ/IIR mods. May need to be modified as right now it just removes all IIQ and IIR mods from extra auras and items.
