forked from github/cordova-android

- Removed BinaryEcho; made Echo support a new binaryEcho action. - Added CordovaArgs wrapper for JSONArray, and a new overload for execute that accepts a CordovaArgs. There is now a default implementation for the JSONArray version of execute that builds a CordovaArgs and calls that version of execute. The default implementation for the CordovaArgs execute is to return false. - Added byte[] version of success() in CallbackContext.
