generate svg of DBICTest::Schema in author mode

 * Use SQL::Translator and GraphViz to produce an svg of the DBIC test
   schema layout.  The new file is examples/DBICTest/db-diagram.svg
   and will be generated when the Makefile.PL is run in author mode.

 * Add GraphViz to DBIC::Optional::Dependencies's dist_dir group
