[Doc-SIG] Updates to Docutils

[David Goodger]

I've just checked in a bunch of changes to Docutils.  The biggest change was
the addition of a command-line interface to the front-end scripts.  Greg
Ward's Optik package is now required (http://optik.sf.net/).

I added ``docutils.frontend`` to support command-line processing of
front-end scripts (which are now down to 3 lines each).  The
``docutils.core.Publisher`` class and ``publish`` function have been greatly
simplified by the use of Optik.
