multiple egos with activated abilities

[Stuntofthelitter]

Example: Bladed iron helm of sanctity

Both egos have an ability tied to them (Skullcracker, Circle of Sanctity) but only one can appear on an item. In this case the item has skullcracker and not circle of sanctity.

Ideally egos with resolvers.charmt() should be mutually exclusive to prevent this. Current implementation comes across as a bit sloppy (or confusing, which is why it was brought to my attention).

Also, when the same ego gets rolled twice, there probably should be a +1 talent level bonus to the ability.
