Converted the results viewer window to handle the new user function GUI page design.

Better support for running a script and the GUI from the command line.

The script is now run at the very end, after all of the GUI is set up, and is run with a
wx.CallAfter call.

Spelling fix for the spin loading wizard.

The spin loading wizard is now accessible from the tree's root menu in the spin viewer window.

Added a toolbar button to the spin viewer window to launch a wizard for loading spins.

A simple wizard has been created for the spin viewer window for loading spins which directs the user
to either the sequence.read user function or the structure.read_pdb and structure.load_spins user
functions. The wizard page Load_method_page has been added at the start to allow the user to choose
the method, and the last page Finish_page has been added so that the wizard can have a finish
button and terminal page.

Added a 32x32 sized relax icon for the spin.

Fix for the updating of the user function menu items in the main GUI window.

This was using the old self.entries_uf data structure.

The spin viewer window now uses the full user function menu of the Uf_menus class.

This should now remove the MS Windows bug whereby the spin viewer window would disappear to the back
after closing of the user function wizard dialogs.

Fixes for the auto-analysis wizards for the new user function GUI page design.

Fixes for the GUI tests for the new design of the user function GUI pages.
