Updated the Addon to use the updated APIs.  Updated the request to use a proxy instead of going directly through Tor.  Removed the Widget and added a ToggleButton
Added a preference validator to make sure the preferences were set before starting the datawake.
Added the number of Page visits to the panel until badges are added to the sdk
Fixed the default port value and added the required step to the readme.
Added a few javascript enhancements.  Removed the parseEntities in the panel js file and just parse them once in the addon code.
Abstracted some code into methods.  Switch in to hasOwnProperty.
Added .join to the body, just incase onDataAvailable ran more than once.
