AUv3 support

[joosties]

To be honest, I'm not sure that's the case. What I do know is, I use in my AUM setup two apps that use IAA, Bandhelper and IK Sampletank. They are the only two apps I have crashing issues with. The rest of my plugin apps are AUv3 apps. No issues with them. I just saw today the BH app doing a automatic update. Nice adding the helper baloons  .  I will test it more thoroughly and come back to you if I still experience any issues
