Created a screenshot of the relax prompt UI mode.

The http://www.nmr-relax.com/index.html title now includes all supported analysis types.

This is to help with web search indexing.

Shifted the screenshots into its own webpage http://www.nmr-relax.com/screenshots.html.

The screenshots were originally part of the http://www.nmr-relax.com/features.html page, but are now
separated. The http://www.nmr-relax.com/screenshots.html page has been also added to the side menu.

The FAQ side menu entry link title has been expanded for the http://www.nmr-relax.com pages.

Editing of the http://www.nmr-relax.com/faq.html page.

Nicer screenshot layout on the http://www.nmr-relax.com/features.html page.

Massive expansion of the relax GUI screenshots at http://www.nmr-relax.com/features.html.

Now most GUI elements have a screenshot, and clicking on the mini-version on the webpage will open
the full sized version of the screenshot.

Preparation for new relax GUI screenshots.

Fix for the title of the analysis selection wizard GUI element.

Updated the GUI description on the http://www.nmr-relax.com/features.html page.

This includes a lot of formatting fixes. The Bieri et al., 2011 reference has also been added to
http://www.nmr-relax.com/refs.html.
