Updated the Bieri et al., 2011 reference as the relax GUI paper is now published.

Fix for the CSA value in the value.set() GUI wizard image.

This was reported by Seb at https://mail.gna.org/public/relax-devel/2011-06/msg00040.html
(Message-id: <4DEE3D12.4000406@...>).

Fixes for the spin.copy() GUI user function element.

This still had remnants of the residue.copy() window.

Comment fix.

Not selecting a peak list file also vetos the event so the cell is not editable.

The 'Rx peak lists' column name is no longer plural.

Added a title and nicer spacing for the relaxation peak lists GUI element.

Removed some unused variables.

Double clicking on the peak list cells in the Rx frames now runs openfile().

Spacing fix.
