Changed the order of the two relax versions being compared for user function changes.

This is in the diff.py script and log file and the user_function_changes.txt document.

Added all user function ranamings since relax 1.3.1 to the translation table.

These were taken directly from the docs/user_function_changes.txt document. Earlier relax versions
are far too different, so this will be the earliest relax version for this translation table. The
relax 1.2 and earlier (and 1.3.0) versions used the run argument throughout and the scripting was so
different, that telling the user how to upgrade to new user functions is pointless. And the release
date of relax 1.2.15, the last of these old designs was in November 2008.

Added all remaining user function ranamings since relax 2.0.0 to the translation table.

These were taken directly from the docs/user_function_changes.txt document.

Updated the user_function_changes.txt document.

This now lists all changes in the user function naming from relax version 1.0.1 all the way to relax
3.3.0.

Added the relax 1.0.1 to 1.2.15 user function printouts.

The diff.log file has also been updated with all of these versions.

Changed the behaviour of the script for showing user function difference between relax versions.

The relax versions are now reversed so the oldest version is at the bottom of the difference
printout.

Added the relax 1.3.0 to 1.3.4 user function printouts.

Created a script for printing out all user functions for relax 1.2 versions.

This also includes the relax 1.3.0 to 1.3.4 versions.

Updated the relax 1.3 user function printout script and added many printouts.

The printouts are for relax versions 1.3.5 to 1.3.16. The earlier relax versions used the relax 1.2
user function setup.

Stripped out all of the relax intro and script printouts from the user function listing files.

This allows the diff.py script to be simplified.
