Fix for the residue.create res_num arg unit test.

This can now be None in relax!

Fix for the eliminate user function prompt unit test set up.

These tests now run.

Fixes for the changes to the pymol and molmol macro user function arguments.

The colour args have been split up into a name and RGB list now.

Fix for a number of user function definitions.

These problems were picked up by the unit tests.

Fix for the state.save user function definitions - the compress_type arg cannot be None!

Converted all of the prompt unit tests to the new auto-generated user function design.

Updated the model-free auto-analysis GUI test to pass.

Changes include opening and closing the about dialog, loading the sequence via the spin viewer
window - testing this GUI element for the first time and the use of the methods behind the specific
value.set buttons.

The model-free GUI auto-analysis 'About' dialog is now stored as a class instance variable.

This allows it to be manipulated remotely, for example by the GUI tests.

The GUI user functions are now going straight to the back end rather than through the prompt.

The GUI user functions were previously passing through the prompt UI user functions for argument
checking, which then passed on to the back end. Now the prompt is bypassed, and the back end is
being directly called. This should speed up the user functions, and specifically the GUI tests.

The prompt UI versions of the auto-generated user functions are now stored in self._uf_dict.

This is a dictionary whereby the keys are the full user function names as text. This is designed
for speed, so that the user function object can be retrieved much faster.
