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.

Fix for the relax 1.3 user function extraction script.

Created a script for printing out relax 1.3 user functions.

Shifted the user function listing script into the test suite directory where the results are.

Modified system test to follow the new functions in the auto analysis.
