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.

Fix for the new analysis GUI wizard - two model-free analysis buttons were present.

This is due to an imperfect merge of the relax_disp branch back to trunk.

Removal of the value_write_fixes branch.

As the relax_disp branch has been merged to trunk, and this branch contains zero commits, it would
be easier to create this branch again from the trunk when needed.

Removal of the svn_merge branch as it has now been merged to trunk.
