Bards and thier code changes

[Zuesrooster]

Tested it the only change is where it adds in the extra points for singing and instrument mastery it should be

if(IsClient())
	{
		if(spells[spell_id].skill == SINGING)
			effectmod += 20*this->CastToClient()->GetAA(aaSingingMastery);
		else
			effectmod += 20*this->CastToClient()->GetAA(aaInstrumentMastery);
	}

as stated on the first message, it only mods it by increments of 10%. Tried playing around with the struct, different values nothing i could make sense of resulted.
