The Monte Carlo simulation state is now turned off after the MC analysis is complete.

This allows the user to make slight modifications and rerun the analysis and optimisation. The
monte_carlo.error_analysis user function switches the state at the very end, just as
monte_carlo.setup switches the state to on.

All of the major GUI and X freeze fixes of r14559:14561 have been ported to the relax data list.

The fixes for the spectrum list GUI element are now present in the relaxation data list GUI element
as well, as the same problems occur in both code paths.

Fix for the size_cols() method of the spectrum list GUI element.

With the asynchronous updating of the element, sometimes the columns are not setup prior to a
size_cols() call.

Bug fix for the freezing of X windows!

The spectrum list GUI element is now updated with a CallAfter call so that the element is updated in
a thread safe way. Without this, the entire X windows system would sometimes freeze!!!

Bug fix for the freezing of the GUI.

The spectrum list GUI element was trying to update itself during execution lock, causing races if
the spectrum data structures in the relax data store are being modified as the GUI element update
is occurring. This would result in a hard lock of the GUI!

Clean up of the debugging printouts from the status module.

The relax execution lock now has debugging print outs.

The status container instance is now private in the Relax_lock objects.

The fake_lock variable in the status module classes is now private.

Added some debugging print outs for the GUI interpreter object.
