Adding support for Convalescence & Healthy Aura, plus cleaning it up a bit since GetAA() will return 0 by default.

In zone/client_mods.cpp, change this

	if (GetAA(aaInnateRegeneration) >= 1){
		hp += GetAA(aaInnateRegeneration);
	}
	if (GetAA(aaInnateRegeneration2) >= 1){
		hp += GetAA(aaInnateRegeneration2);
	}
	if (GetAA(aaNaturalHealing) >= 1){
		hp += GetAA(aaNaturalHealing);
	}
	
	hp += GetAA(aaBodyAndMindRejuvenation);

to this

	// AA Regens
	hp += (GetAA(aaInnateRegeneration)
		//+ GetAA(aaInnateRegeneration2) //not currently in the AA table anymore, so why bother?
		+ GetAA(aaNaturalHealing)
		+ GetAA(aaBodyAndMindRejuvenation)
		+ GetAA(aaConvalescence)
		+ GetAA(aaHealthyAura)
	);
