relax SVN archive

Added the repositories section of the web chapter of the manual.

Created the web site, mailing list, and bug report sections of the web chapter of the manual.

Added an outline of the new chapter about the web sites, mailing lists, bug tracker, and
repositories.

The hyperref LaTeX package is now used in the relax manual.

All websites were changed from \texttt{} to \href{}{} to create links.
The links were formatted to all be blue without a box around it.

Removed the spaces in front of the \index{} commands from the manual LaTeX source files.

These spaces were causing formatting problems in the compiled manual. This included spaces between
the last word of a sentence and the full stop.

Added the committers file.

Fixed a number of tests in the test suite which were pointing to the wrong directory.

Renamed the main test suite file and changed its class name.

Shifted the test suite from the directory 'testing' to 'test_suite'.

Set notation fix: Changed the square and round brackets to curly brackets and replaced ':' with '='.
