relax SVN archive

Updates to many frame order test suite shared data relax scripts.

These scripts are used for data generation and display, and are not part of the test suite. The
updates are for the frame_order.pdb_model and pymol.frame_order user functions which no longer
support the 'dist' keyword argument (this functionality was shifted into the frame_order.simulate
user function).

Expanded the release checklist instructions for creating the README.rst files.

Added release instructions for creating the README.rst files for the download area.

This is for using the custom html2rest at ttps://sourceforge.net/p/nmr-relax/code-python-html2rest
to automatically generate the reStructuredText file from the wiki release notes.

Even more div box fixes.

The "Protein dynamics" and "relax libraries" sections have been split into a "main_box" div box.
