Speed ups for the Relax_disp.test_bug_21460_disp_cluster_fail system test.

The optimisation precision is not important for demonstrating this bug.

Created the Relax_disp.test_bug_21460_disp_cluster_fail system test.

This is to catch bug #21460 (https://gna.org/bugs/?21460) reported by Min-Kyu Cho (min-kyu dott cho
att live dot com).

The save file added to the repository consists solely of the data for the first residue.

Updated the relaxation dispersion model list on the dispersion analysis webpage.

This is at http://www.nmr-relax.com/analyses/relaxation_dispersion.html.

CSS fixes for the webpage http://www.nmr-relax.com/events.html.

Initialized merge tracking via "svnmerge" with revisions "1-21949" from
svn+ssh://bugman@.../svn/relax/trunk

Creation of a dedicated branch for developing the double rotor model of frame order.

Implemented to read spins from a SPARKY list, when no intensity column is present.

Addition to Support Request #3044, (https://gna.org/support/index.php?3044) - Load spins from SPARKY list.

Partial fix for bug #21338 (https://gna.org/bugs/?21338) - the bad sRGB profile in some PNGs.

This is only partial as some files are still to be converted (the original Bruker logo, and the
16x16, 22x22 and 32x32 sized Bruker icons).

Modified sparky file to have no columns with intensity.

Copied sparky list to be modified for sparky file without intensity column.
