Refactored BonjourPlugin to put communication into JS

Ross,

I read your great article on your Bonjour Plugin.  I've refactored it quite a bit to put it into more of a standard PhoneGap style.  I also moved some of the communication logic to JavaScript.  However, I wasn't able to finish the refactor.  Some of the Objective C can certainly be cleaned up.  

Feel free to incorporate any of these changes into your repo.

If you have any questions, don't hesitate to contact me.

Sincerely,
Jeff Schwartz
