The opening of the results viewer window after an analysis is now thread safe!

There is now an observer object for the execution lock.

The text redirection to the relax controller is set up in the controller, so this removes repetition.

The redirection was happening in the controller first, and then again in each analysis.

Modified how the auto_analysis status object behaves so setting values causes an observer to be notified.

Removed some unused imports.

The fonts are now set for all parts of the wizard pages.

The results display window is now shown at the end of the auto-analysis execution.

Updated the NOE GUI auto-analysis.

The ref and sat Grace files are now added to the results list, and the save file is no longer
created.

A busy cursor is now shown while waiting for the new analysis wizard.

The save_state flag has been added to the NOE auto-analysis so that the save state can be turned off.
