More independence for the wizard_elements - the height of the element must now be passed in as an arg.

Started to make the wizard_elements module classes independent of the wizard.

The references to parent._div_left have been eliminated, this is now expected to be passed in by the
parent which has that variable as the divider arg.

Removal of an unused class variable.

Added the user_functions.script module which should have been committed in r16303.

Converted the Interpreter.script() method into a proper user function.

This pseudo user function was no longer functional after the auto-generation changes.

Removed some junk text.

Redesigned the prompt help system for the auto-generated user functions.

The documentation is closer to the style in the relax manual, including 'Synopsis' and 'Default'
sections (i.e. see http://www.nmr-relax.com/manual/value_set.html).

The _build_doc() method now returns the documentation.

Eliminated the build_doc() function as this is no longer used.

The new auto-generated user functions use a variant of this function as the _build_doc() method.

The uf_docstring functions are no longer private.
