Warlock Pet Re-Summon on Strategy Change

Hello everyone,

This PR addresses issue #1464 - Now, when you change a strategy, the new pet will be summoned accordingly - as long as the warlock knows the pet. I tested this myself with level 80 warlocks, then moved to lower level warlocks. It was nice to see that when my affliction warlock went from level 29 to 30, it automatically summoned the felhunter (while having the succubus out prior).

List of changes per file:
src\AiFactory.cpp: Set default level 1 spec to demonology for altbots - it was affliction prior. This will allow them to use Curse of agony, corruption, and immolate between levels 1-10.

src\strategy\warlock\GenericWarlockNonCombatStrategy.cpp: Added the "wrong pet" trigger to each of the 5 pet strategies, coupled with the appropriate summon action.

src\strategy\warlock\WarlockAiObjectContext.cpp: Registered the "wrong pet" trigger and moved the unstable affliction static trigger all to 1 line, cleaning it up a bit.

src\strategy\warlock\WarlockTriggers.cpp: Added the logic for the wrong pet trigger here. I tried to leave detailed comments as much as possible explaining it's thought process.

src\strategy\warlock\WarlockTriggers.h: Added the WrongPetTrigger.
