Thanks to some help from @rondlh I added version pinning to CaDoodle. Unlike pervious update, you will need to gett the latest installer from: https://github.com/CommonWealthRobotics/CaDoodle/releases for this new feature to work. You can pin your CaDoodle to a specific version, and CaDoodle will not use any internet connections whatsoever from first click to working application. 

Current releases of CaDoodle include a zipped up copy of the online assets needed by cadoodle, in the git cache directory that CaDoodle expects them to be in. The instaaller downloads this zip with any new update, and the Application unzipps the zip into the correct location each time it loads to ensure the assets match the version this application expects to be there.
