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.

The generic_fns.pipes.pipe_names() function now can restrict the list of names to a specific bundle.

Fixes for both the loading of GUI analysis tabs from a save file and deletion of analysis tabs.

Fix for the pipe editor window when associating pipes with new analyses.

The pipe bundle name is now passed into the auto-analysis code.

The pipe editor window now handles the pipe bundling concept.

There is a new button for the pipe.bundle user function, a new column showing the pipe bundles, and
the pop up menu allows pipes to be associated with bundles if not already bundled.

The pipe.bundle user function back end now notifies all the pipe_alteration observers of the change.

This is required for proper GUI interaction.

Refinements to the pipe.create user function definitions.
