Added support for Cordova 3.x

Hi, your video plugin is awesome. It solved a big problem for me. I had to modify the code to make it work on the Cordova 3.x version as the plug in architecture seems to have changed. I forked the project and added the new source code. Please do pull it in the main repo if you feel it might be useful.

This is my first contribution in open source and in Github. Do let me know if there is any problems with the format or coding standards.

Arun
