Add support for changing ports.

This commit adds a combo box for selecting ports.
Overall this implementation could have taken two paths:
 * Implement port selection as combo box.
 * Implement port selection as a button.

I went for the first option as is done in selecting card profiles over the
second method used for selecting devices for streams. This seems more like
how a config option should be presented as opposed to a runtime type thing.
