adding the cordova folder for the native support of cordova plugins

Adding a folder named "cordova" which contains a main file named cordovaSocket.py which is called by the apisocket.py with the parameter as given by the javascript call. This then calls the appropriate function of the required plugin.All the various plugin codes are written in there respective files.
You need to add a copywrite notice to the top of every file (you do deserve some recognision for writing all this code :smiley_cat:).  We use the GPLv2, so the notice should look like:
