Wizard port assistance

[hsorby]

Currently the port Object is a line edit and doesn’t give the user any guidance on what to fill this field. It is not obvious that the user should have to enter “http://physiomeproject.org/workflow/1.0/rdf-schema#images” to be able to make their port compatible with ports from existing plugins. Perhaps we could suggest a list of common port types when the user starts typing in the line edit?
