relax SVN archive

Added support for launching the Bieri GUI.

The presence of the wx Python module is now being tested, and an appropriate error message printed when missing.

Renamed the relaxGUI module to match the relax naming conventions.

Removed some *.pyc files that were accidentally committed to the repository.

Converted the relaxGUI code into a Python package.

Renamed bieri_gui to gui_bieri.

Command line opts for launching the GUI mode (-g, --gui) and the specific Bieri GUI model (-b, --bieri).

The wrong README file was committed in the previous commit!
