Return column definitions to portsPage (gui fails to load otherwise).
fcontextPage:
"ftype" dropdown was filled from 2 sources (system-config-selinux.glade
and fcontextPage - from seobject module) which resulted in duplicate
and invalid options. When given to "semanage fcontext -f", ftype has to be
converted to 1 letter argument mode.
TreeView.get_selection().get_selected() can return "None" if no item is selected
(the list can be empty). Test if correct iterator was acquired.
