Add API docs to appsensor.org

[jtmelton]

Need to add the API docs as part of the release process (under versioned subdirectories). Also need to add any generated WSDL / REST api docs. Consider tooling to help with REST docs (swagger, etc.)

Making progress here, should be adding docs this week or next.

I just pushed a change to the website. You can now retrieve both the javadoc as well as the rest api documentation (via auto-generated swagger - using enunciate library). The links are here: http://appsensor.org/api.html . Updating this will now become part of the release cycle. (Note: the "try it out" links will be dead as this is not a real appsensor server.)
