The spin.name and spin.element user functions in the BMRB system and GUI tests now use the force flag.

The flag is set to False. This is to try to replicate the old behaviour of the test and to allow it
to pass again.

Another set of fixes for the bad merge at r16679.

For some reason the branch changes to the generic_fns.align_tensor module had been reverted in the
merger.

Bug fix for the loading of the molecule name and type from relax state or results files.

The str() builtin function is now used to convert the string from unicode to a normal string. This
is needed as u'My mol' != 'My mol', breaking a number of tests!
........

The BMRB icons now also have transparent backgrounds.

Made the background of the BMRB wizard graphic transparent.

This just looks better.

Created a dummy menu entry called 'File->Export for BMRB deposition'.

The back end code, which will be an export wizard, does not exist yet.

Fix for the spectrum list GUI element for a bug introduced at r16705.

The spectrum and relaxation data list GUI elements now use graphics.fetch_icon for all icons.

Renamed some of the methods in the relaxation data list GUI element.

The spectrum and relaxation data list GUI elements now use the user function definitions for icons.
