The Scons compilation of the PDF and HTML manuals now checks for replicated titles.

A new replicate_title_check target has been added to the scons scripts. This calls the find()
method of the replicate LaTeX title finding script to determine if any titles are replicated, and if
so the scons target returns with a sys.exit(1) call. This target is set at the start of the
user_manual_pdf, user_manual_pdf_nofetch, user_manual_html, user_manual_html_nofetch scons targets.

The result is that the manual cannot be compiled if replicate titles exist, forcing the titles to be
changed. The result will be that the HTML pages at http://www.nmr-relax.com/manual/ will all be
unique, as replicated titles results in only one HTML page being created for all the sections.

Removed the duplicate LaTeX title finding shell script.

This is now handled by the far more advanced Python script.

Renamed the replicate title finding script.

Converted the replicated title finding Python script to use a class structure.

This allows the script to be imported as a module. The replicate finding has been shifted into a
find() class method.

Converted the duplicate title finding shell script into a Python script.

The Python script is far more advanced and uses a different logic to produce a table of replicated
titles and their count. The script also returns a failed exit status when replicates exist.

Updated the shell script for finding duplicated titles in the LaTeX files of the manual.

Removed a double full stop from the Softpedia link at http://www.nmr-relax.com/links.html.

Added a number of redirects.

This includes a link to the API documentation which changed names during the development of the 3.3
and 3 errors in user function links to the manual in the relax release notes.

More minor changes to the 'Announcement' section of the release checklist document.

One more wiki instruction about checking for dead links in the release checklist document.
