relax SVN archive

Updated the title of http://www.nmr-relax.com/features.html to include the theories supported.

Expanded the title of the index.html file for http://nmr-relax.com.

This was 'relax' but is now 'relax - NMR molecular dynamics analysis'.

Changes to the main relax webpage at http://nmr-relax.com.

Formatting of the epydoc exclusion list.

The multi-processor test implementation scripts are now excluded from the API documentation.

The import of the scripts was failing, and they are not part of the relax API.

The setup.py script can now be imported for the epydoc API documentation system.

Epydoc docstring fix.

The extern and minfx.scipy_subset relax packages are now excluded form the API documentation.

This will be updated at http://www.nmr-relax.com/api/ after the next relax release.

Some changes to the menus in the http://nmr-relax.com pages.

Reorganisation of the relax API documentation (http://nmr-relax.com/api/).

The relax 1.2 documentation has been removed as this version is incredibly old. The
http://nmr-relax.com/api/index.html has been deleted, and the entire 1.3 documentation now resides
in http://nmr-relax.com/api/.
