Added the GUI analysis current_data() method for returning the data store container.

The auto-analysis status objects are now set up for all auto-analyses.

The auto-analyses status objects now have a completion flag 'fin' to indicate if the analysis is complete.

Added a new analysis method current_analysis_type() for determining the current analysis type.

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.
