Editing and fixes for the relax 4.0.0 part of the CHANGES file.

Fixed the date on the download page for relax 4.0.0 - it was tagged on the 7th of Oct.

Updated the http://www.nmr-relax.com/download.html webpage for the relax 4.0.0 release.

Removed two old pages from the HTML manual at http://www.nmr-relax.com/manual/index.html .

These are for the no longer existing frame_order.average_position and frame_order.num_int_pts user
functions (the first was deleted, the second is now called frame_order.sobol_setup).

Updated the relax HTML manual at http://www.nmr-relax.com/manual/index.html to version 4.0.0.

Ported r28040 from trunk to allow the HTML manual to be compiled.

The command used was:
svn merge -r28039:28040 svn+ssh://bugman@.../svn/relax/trunk/ .

Fixes for sub and superscripts throughout the manual.

This introduces {} around all sub and superscripted \textrm{} instances. This is not needed for the

of the manual compiled by latex2html, which requires the correct notation. The fixes are for both
the new frame order chapter as well as the relaxation dispersion chapter.
