relax SVN archive

Added some graphics and icons from Grace.

Added the 'Help->Licence' menu entry (this is a simple copy of 'User functions->gpl').

Added a graphic for the GPL licence.

Implemented the gpl user function in the GUI.

The results file viewer 'open' button is now partially functional.

Missing import of misc.open_file().

Shifted the file opening code of the relax_manual() method to the misc.open_file() function.

This code is general for opening any type of file, so has been abstracted.

The results viewer window now uses cdp.result_files.

This decouples the files and their creation from the GUI. The open button does not currently
function.

Files created by the grace.write user function are now put into a new list cdp.results_files.

This is a list of lists, with the sublist composed of two elements. The first is an identifier
string such as 'grace'. The second is the file name.
