relax SVN archive

Reverted r26820 as this was incorrect.

The command used was:
svn merge -r26820:r26819 .

Modified the relax_fit_saturation_recovery.py script to work as a system test.

This is the script from Andras Boeszoermenyi <Andras_Boeszoermenyi att hms dott harvard dot edu>.
The change follows from the discussion of
http://thread.gmane.org/gmane.science.nmr.relax.devel/7308/focus=7369.

The status.install_path variable is now used to point to the location of the files. The relax data
store ds.tmpdir variable is used for outputting all files. And commented out user functions have
been deleted.

Added a copyright notice for Andras Boeszoermenyi for the newly added saturation-recovery R1 script.

This change follows the discussion in the message
http://thread.gmane.org/gmane.science.nmr.relax.devel/7308/focus=7369.

Added a system test script for testing the saturation-recovery R1 experiment.

This was created by Andras Boeszoermenyi <Andras_Boeszoermenyi att hms dott harvard dot edu>. The
file was taken from the saturation_recovery.tar.gaz file
(https://gna.org/task/download.php?file_id=22997) are attached to the task at
http://gna.org/task/?7415. The only difference with the original script is that the grace.view user
function calls have been removed, as these cannot be used in a system test.

Added systemtest Nmrglue.xtest_plot_hist_cpmg_several to test the histogram plotting of several spectra.

This can be useful when loading many spectra and assigning spectrum IDs.
