relax SVN archive

Updated the open source infrastructure chapter of the relax user manual.

The relax 1.2 versions used as examples in the chapter are far too ancient!

Added a screenshot of the new relax 1.3.15 version in script mode.

This adds the ANSI text colouring and makes the screenshot more interesting.

Significant updates to the introduction chapter of the relax user manual.

The text has been updated to match the current relax versions. All mention of the dead SRLS theory
has been eliminated. Screenshots of all the GUI windows and analyses have been added to prettify
the chapter, and the text for the GUI has been rewritten for the new GUI design.

The alignment tensor user functions can now all handle the situation whereby no tensors exist.

This was previously giving non-informative Python tracebacks.

Added a number of GUI screenshots for use in the relax user manual.

These were taken from http://www.nmr-relax.com/screenshots.html.

Added colons to all entries of the abbreviation chapter in the relax user manual.

Updated and completed the installation chapter of the relax user manual.

A lot of the text was 4-6 years out of date.

Fix for the scons 'install' target for the byte-compilation of the *.pyc files.

Running 'relax --test' no longer byte-compiles the files, so instead 'python -m compileall .' is
being used instead.

Fix for the chi2 references in the maths chapter of the relax user manual.

Expansion and completion of the model-free chapter of the relax user manual.

A large number of changes have been made to complete the chapter and description of all model-free
sample scripts. The dauvernge_protocol.py script is now fully described.
