Fix for the HTML user manual at http://www.nmr-relax.com/manual/relax.html.

The ignore_commands function is now being used to force latex2html to ignore \linebreak[0] commands.
These were previously putting the text '[0]' throughout all the HTML pages, and were especially bad
in the user function section.

Fix for the HTML user manual at http://www.nmr-relax.com/manual/relax.html.

The document splitting has been restored to a split depth of 5. This had been changed to make the
main chapters of the text more readable, but the user function document is now far, far too long and
is a massive strain on browsers, so the behaviour has been reverted.

Updated the ancient COMMITTERS which hasn't been changed in over 4 years!

The pipe editor window is no longer centred, now matching the behaviour all other windows.

All open relax windows are now closed prior to running the test suite within the GUI.

Exiting the GUI now only warns about data loss only if there is data to loose.

The relax data store is_empty() method is being used to skip the question dialog, allowing relax to
be shut quickly.

The relax controller can now not be closed while the test suite is running.

This presents uses from doing silly things, and then reporting it as a bug!

During the GUI tests from the GUI, the relax controller is now modal.

This is to stop users from doing silly things!

Shifted the code of r15803 from the test suite into the GUI method for running the test suite.

The relax controller now stays on top of all windows when the GUI tests are being run.

This improves the running of the GUI tests in GUI mode on Mac OS X and MS Windows.
