- Fixing Trac #173. The unused states are now excluded from the graph.

- The path to graphviz installation (dot executable) is now configurable via the 'graphviz_path' config variable (defaults to /usr/bin/dot).
- If graphviz is present, the graph is generated on the fly, and using the current user's localization/translation for the state & transition names.
