Removed the \pycodestar{} references in the development chapter.

This command has been deleted as \newcommand cannot have \verb inside it! The \pycodestar{x}
references have been changed to \verb*!x!.

Removed \verb from the \newcommand definitions as that is forbidden in LaTeX.

Now Python code is formatted using a small TT font.

Added a section label to the intro chapter of the user manual.

Modified the dauvergne_protocol sample script to handle tryptophan indole NE1 data.

The citations chapter is now included in the HTML version of the user manual.

For some reason, a file named 'cite.tex' cannot be handled by latex2html.

The latex2html compilation of the user manual now ignores the \bibitem{} commands.

This is needed for the HTML version of the user manual.

Fixed a section titled 'Introduction' clashing with the intro chapter of the user manual.

Fixes for the user function icons in the HTML version of the user manual.

These icons are now placed on the correct HTML page.

Removed the text '.eps.gz' from all of the LaTeX included graphics in the user manual.

This allows latex2html to select and use the PNG images instead, producing much better graphics for
the online manual (http://www.nmr-relax.com/manual/index.html).

Fix for the graphics.fetch_icon() function for when no file format is specified.
