Added some Molmol graphics.

Converted the molmol and pymol user function docstrings to the new design.

Alphabetical ordering of the structure user function menu entries.

All of the boolean_selector SetValue() calls have been changed to the 'default' arg.

This will allow the boolean_selector object to be changed into anything, and all user functions
should still be 100% functional.

Implemented the structure.get_pos user function page and menu entry.

Implemented two more of the structure user function pages and menu entries.

These are:
structure.create_vector_dist
structure.create_diff_tensor_pdb

The wizard graphics are taken from my paper:

d'Auvergne, E. J. and Gooley, P. R. (2008). Optimisation of NMR dynamic models II. A new methodology
for the dual optimisation of the model-free parameters and the Brownian rotational diffusion tensor.
J. Biomol. NMR, 40(2), 121-133. (http://dx.doi.org/10.1007/s10858-007-9213-3).

Modified the dauvergne_protocol auto-analysis to be able to loop over all the global models.

The diff_model arg can now be a list of global model names, allowing the protocol to loop over each
diffusion model.

The warning about open windows slowing calcs now includes the results viewer window.

The refreshing of the results viewer window is now thread safe.
