Shifted the dispersion chapter of the user manual to its correct position.

Somehow during the relax_disp branch merger, this chapter was shifted into the "Advanced Topics"
partition of the manual.

Fix for the GUI tests for a wxPython 2.9 ListCtrl.HitTest() bug.

This only affects the relax test suite. The suite should now pass on all systems.

Fix for two system tests to prevent relax save files from being dumped in the installation directory.

This would have been fatal for the tests suite on systems with relax installed as root.

Bug fixes for the molecule.delete, residue.delete and spin.delete user functions.

The molecule, residue, and spin metadata in the relax data store was not being updated correctly
after these user function calls so that any subsequent operations on this data was failing. This
metadata problem was not noticed before as it disappears if the state is saved and reloaded into
relax after a restart.

Attempts at fixing and improving the Relax_disp.test_hansen_trunc_data GUI test.

These changes have uncovered a spin ID updating problem in the relax data store after calling the
residue.delete user function.

Fix for the Wiz_window.setup_page() method.

The user function SetValue() methods are no longer called but instead the Uf_page.SetValue() method
is used to set up user function arguments. This is important as this later method can properly
handle the free file format arguments and other special arguments whereas the former cannot.

Bug fixes for a number of broken Oxygen icon lookups in the GUI.

Fixes for the Relax_disp.test_tp02_data_to_tp02 GUI test.

This should have been fixed in the relax_disp branch.

Fix for the Noe.test_noe_analysis system test.

The old Grace file was turning the legend first off and then on, but now this is fixed.

Fixes for the lib.software.grace for an imperfect merger of the relax_disp branch.
