Applied a spell check to the 'Licencing' chapter of the manual.

Created the 'Licence' chapter in the manual.

Bug fix:

Half of the keyword arguments were being skipped by the 'fetch_docstrings' script.

Replaced unnecessary double quotes with single quotes in some user function docstrings.

Added a relax copyright notice to the 'fetch_docstrings' python script.

Bug fix:

The docstring to LaTeX script now correctly translates special parameter names found at the start
of a line.

Changed the formatting of all tables within relax's docstrings.

The lines inbetween individual rows have been removed.
These tables are now correctly displayed in the manual.

Fixed a bug in the quote environment (not starting a newly created line).

Example shell commands beginning with '$' are now placed in the example environment.

Quotes now have their own environment and the examples have been fixed.

All quote in the docstring are now placed on there own line and are inside the environment
\quoteenv{}. The only exeption are the quotes in the example environment.

Every second example, starting with 'relax>' was being skipped and three line examples were failing.
This has now been fixed.

The text 1st, 2nd, etc are now printed as 1$^\mathrm{st}$, etc.
