The auto-analysis initialisation can now associate with a pre-existing data pipe.

This is useful for bringing a data pipe into an analysis tab.

The data pipe editor now has a new 'Associate with a new auto-analysis' menu entry.

Added a hybridise button to the data pipe editor.

The pipe.hybridise user function window now uses the new Combo_list GUI element for pipe selection.

Created the Combo_list GUI element for presenting a dynamic list of combo boxes.

This is designed as a class rather than a wizard method to make it more extensible.

Created the pipe.hybridise user function page and menu entry.

Added a wizard version of the pipe.hybridise graphic.

Added the pipe_hybrid icons to the paths module.

Created icons for the data pipe hybridisation.

Fix for the GUI analyses object - the reset() method no longer unregisters from the observers.
