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.

The graphics.fetch_icon() function argument 'format' can now be set to None.

This will return the file path without the extension.

Elimination of all duplicated chapter, section and subsection titles in the user manual.

This fixes bug #20185 (https://gna.org/bugs/?20185).

The HTML files for the user manual now have longer names - this is needed for removing the duplicates.

Fix for the duplicate title finding script - the LaTeX and HTML mode alternatives are no longer mixed up.

Improvements to the duplicate user manual title finding script.

Created a simple shell script to find duplicate titles in the relax user manual.

This is important for the HTML version of the manual as duplicated titles causes HTML pages to be
overwritten. For example all chapters, sections and subsections titled "Introduction" will load the
introduction.html file which will contain the text of the last section with that title!

Additions to the scripting section of the relaxation curve-fitting chapter of the user manual.
