The GUI and logging/teeing modes are now compatible with each other.

The relax controller now uses the relax_io.SplitIO class to allow the STDOUT and STDERR messages to
be both directed to the log file and the controller. The controller will capture both streams,
rather than splitting the IO, if no IO redirection has been set up.

The list of figures in the relax user manual is now on a new page.

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A lot of the text was 4-6 years out of date.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