relax SVN archive

Instead of opening http://www.nmr-relax.com/refs.html in a browser, a HTML window is now being used
to display all relevant references. The refs are coming from the info container.

This is far from complete. To be added are:
- Links "(more)" added to the end of each reference. This will open a new HTML page with the
full information, DOI link, abstract, etc. for each reference separately.
- Make the DOI link open in a brower.
- Make the forward and reverse buttons functional.

The HTML also needs to be prettified.
