Added the 'Tools->Test suite' menu entry. This currently does nothing.

The status.test_mode and status.show_gui flags are now initialised only once in the singleton.

This is to prevent them from being overwritten when a reset() call is made.

Stated to adapt the GUI tests to be able to run with relax in GUI mode.

The bad relaxation data error checks in the model-free analysis are now more informative.

The checks in the model-free analyses for correct ri errors now prints out the spin ID string.

The previous errors only showed the spin number and name, causing confusion

The test suite runner 'tests' arg now defaults to [], which is the proper null value.

Renamed the 'Settings' menu to 'Tools'.

This is to make it more general for the future inclusion of the test suite.

The results viewer window now only executes one user function for the diffusion tensor if PyMOL is missing.

This prevents 3 errors (with windows) from appearing.

Modified the GUI interpreter apply() method to catch RelaxErrors.

Now gui_raise() is used to raise the error and show a dialog, and the method returns the execution status.

The diffusion tensor PDB in the results viewer is now launched by synchronous pymol user function calls.

This prevents the RelaxError appearing 3 times when PyMOL cannot be found.
