The default file name is now passed all the way into the RelaxFileDialog.

This is for the auto-generated GUI user functions.

Improvements to the Selector_dir wizard page GUI element.

The icon is now for a directory open and not file open, the tooltip is also fixed, and the default
value is now passed all the way through.

The auto-generated user functions and classes are now always alphabetically sorted.

The Uf_object.add_class() and Uf_object.add_uf() method now sort the lists at the end. The data
objects are stored in dictionaries to avoid sorting issues.

Created wizard graphics for the select and deselect user function classes.

The spin and spin_grey icons are used for the menus.

Converted the select and deselect user functions to the auto-generation design.

The boolean_doc variable has been shifted from the deleted prompt.select module into the
generic_fns.selection module, where it belongs.

The new icon fetching system is now being used for the relax icons in the menus.

The relax Ulysses butterfly icons are now in the icon directory and in all sizes.

The 16x16 icon has also been improved.

Shifted all the gui/images graphics into the graphics/misc directory.

This finally brings in all of the graphics into one place.

Set the state user function class menu icon to the relax icon.

Converted the molmol user function to the auto-generation design.

For this process, the molmol.macro_apply and molmol.macro_write user function colour_start and
colour_end args had to be split, just as in the pymol user functions. They previously accepted both
a Molmol or X11 colour name or an RGB colour array but are now separate args.
