Register rstHandler to restore experimental reST support

(Experimental) reStructuredText support was working in v0.12,
but was no longer handled after some refactoring in v0.13-DEV.
That experimental support is now restored.

Furthermore, check for both rst2html and rst2html.py in the PATH,
and execute whichever is found.

See #472 for more information.
