Ultimate Combat- Wizard archetypes shouldn't give arcane school abilities

Completed: At revision: 17742

This fix seems to be working if the user had correctly chosen to make the wizard without a specialty (just chosen the normal wizard package). However, if the user creates a specialty wizard and then chooses one of these archetypes, the specialty abilities (eg. touch of the grave and power over undead for a necromancer) and the normal arcane oppositional schools still remain (eg choice of two other schools for a necromancer). Perhaps the easiest way to deal with this, is that if a wizard has chosen to specialize, might be to disable the arcane bomber, siege mage, and spellslinger archetype (since these options replace arcane school specialization anyway).
