Added the 'bundle_to' arg to the pipe.copy user function back end.

This arg is now functional.

The dauverge_protocol auto-analysis now uses the new 'bundle' user function args.

This is used in the pipe copying to place the newly created pipe and in the model selection, both so
that all pipes created during the analysis are located within the pipe bundle reserved for that
analysis.

The GUI user function window titles are now set to the 'title_short' value.

This is because the long title can be far too long for a GUI window title!

The long title or synopsis is now added to the GUI user function description text as italic text.

Added the 'bundle' arg to the model_selection user function specification.

Improvements to the 'bundle' arg specification of the pipe.create user function.

Added the new 'bundle_to' arg to the pipe.copy user function.

This will be used to associated a newly copied data pipe with a pipe bundle.

Added some backwards compatibility code for old GUI state files missing pipe bundles.

Created a GUI test for loading an old relax 1.3 save state containing GUI analyses.

Updated the dauvergne_protocol auto-analysis to spawn all pipes into the named bundle.
