Fixes for the test suite relaxation data creation script.

The code was not fully compatible with the relax 1.3 design.

Added initial support for determining protein connectivities in the internal structural reader.

This is currently only for intra-residue connectivities in the protein backbone. A number of new
methods have been added:
_mol_type()
_protein_connect()
_protein_intra_connect()

Converted the relaxation data generation script from relax 1.0 format to relax 1.3.

Created the PDB representation of the spherical vector distribution for 9 vectors.

Modified the script to only have 3 incs.

Modified the spherical vector distribution script in preparation for Python 3.

Added some old 2004 scripts for creating a uniform vector distribution and calculating relaxation data.

This will be used in the end to build a quick test for the dauvergne_protocol auto-analysis.

Fix for Mac OS X - the wizard buttons are now all of the same size.

SetMinSize() rather than SetSize() needs to be used with wx.ADJUST_MINSIZE!

The dialog Close() rather than Destroy() method is being used to terminate the wizard.

This is necessary for Mac OS X.

Mac OS X bug fit - removed the Destroy() call after ShowModal() in the wizard.

The Destroy() method was actually being called twice, the first time either by the _ok() or the
_cancel() methods, and the second time directly after the ShowModal(). This is fatal on a Mac!
