Title: Fix get_graphviz_version()

Fix get_graphviz_version()'s regexp searching for a version number. Because this used '*', any string matched the expression. On my version of graphviz, 'dot -V' returned 'dot - graphviz version 2.30.1 (20130214.1330)', so get_graphviz_version() returned 'dot' as the version.
