Add the ability to remove ports

[nwoeanhinnogaehr]

The client cannot be running when this is done, because then we may erase from the middle of m{Input,Output}Ports while jackToClassAudioCallback is getting the ports. There's probably a way to defer erasing the port so this can be worked around, but does anyone need to remove ports from a running client anyways?

oh nice, i guess I missed the notification on this one, I'll take a look at it when I have some time and then merge it in. Thanks!

I could see needing to remove from a running client.. say you create then erase an aux bus channel or something?

I also realize now that this doesn't update either the swig interface or the blocking API.

I'm going to put some more thought into how it could be made to work with running clients in the next few days because it became a bit annoying having to reconnect all ports after removing a few.
