Developers specify if ports are north/south / otherwise all east/west

[forresto]

In the new version I was considering ditching n/s ports, but @jonner had the suggestion of making that an option for the component devs. So error ports out the bottom, or control ports into the top of audio processing graph where the main audio pipe goes e/w.

Could this be another aspect of Port metadata (noflo/noflo#120)?

Port metadata sounds like a fine solution to me

SVG implementation doesn't have N/S ports, so I guess we can close this. We have port metadata, however, and could theoretically utilize it if we want to revive this feature at some point.
