Change the implementation bundle for org.json to one with a more open…

… license.

Use

   com.vaadin.external.google : android-json : 0.0.20131108.vaadin1

which has the Apache License 2.0 license:
http://www.apache.org/licenses/LICENSE-2.0

Add source for org.json.JSONString interface, which is missing from
the above bundle.

+--------
+
+This implementation uses a clean-room implementation of the org.json
+library implemented for the Android system, released under the Apache 2.0 license. See
+[com.vaadin.external.google:android-json](http://search.maven.org/#artifactdetails%7Ccom.vaadin.external.google%7Candroid-json%7C0.0.20131108.vaadin1%7Cjar)
+That jar does **not** include the org.json.JSONString interface, so a new implementation of that interface is added to this source.
