DOH may be run standalone by issuing a command like the following:

java -jar ../shrinksafe/custom_rhino.jar runner.js testModule=tests.colors

where the testModule argument is optional and custom_rhino.jar is just a
convenient copy of the Rhino JavaScript engine -- the custom patch is not
required.

Optional arguments include:
 * dojoUrl - specifies the location of dojo.js
 * testUrl - specifies a Javascript file to load with initialization code
 * testModule - specifies a test module in the dojo package namespace
