Use UAT model for I/O graph

Convert from using TreeWidgetItems to UAT model/delegate.  More of the GUI
is "just handled" within the table.
Required to add support for "colors" and "protocol fields" to UAT types.
Also needed to add some hacks for "custom" UAT field handlers for
backwards compatibility with the existing UAT structure used.

Because UAT functionality was switched completely to the model, some
information in the table was "lost in translation" because the UATs
themselves aren't translated to other languages.

TODO:
2. Better "order of operations"?  A bunch of NULL/size checks needed to be added to prevent crashing.
Now with model/"view" should events/functions be reordered?
