relax SVN archive

Big bug fixes.

The structures 'self.relax.specific' and 'self.relax.specific_setup' no longer exist!

Shifted all the specific_fns class imports and initialisations from main.py to __init__.py.

Converted the set() class method into a module function.

Implemented the spin_id unit test for the value.set() user function.

Implemented the param unit test for the value.set() user function.

Bug fix.

The value argment to the value.set() user function has been changed to 'val'. The argument was
clashing with the modules because the names were the same.

Implemented the val unit test for the value.set() user function.

Added the infrastructure for the user function arg unit tests of prompt.value.

Fixed the program intro catch Windows Vista.
