Some playing around with the analysis wizard.

This is going to take some work!

Split Wiz_window into two classes, Wiz_window (dialog) and Wiz_panel (panel).

This will allow a series of panels to be created and strung together in one dialog, i.e. a wizard.

Added the infrastructure for the operation of the 'File->New analysis' menu entry.

The skeleton gui.analyses.wizard.Analysis_wizard class has been created to have the run() method
which returns the analysis type and the data pipe name to the relax_gui new() method.

Added the gui package path to all the GUI imports in relax_gui.

Removed all remnants of user functions from the Wiz_window class.

This includes renaming the add_uf() method to add_contents().

Added a directory for graphics related to analyses.

Shifted gui.user_functions.base.UF_window into gui.wizard.Wiz_window.

This is to allow the code to create Wizard-like windows, to be strung together to form wizards
later on.

Removed the completely unused gui/res directory.

This was ancient rudimentary code and images.

Reverted r13063.
