Add KitKat support

Hello Sylvain,

There are so many apps in the PlayStore  doing the same thing BUT asking for many permissions, so this is why I was using yours (power of open source).
I added the KitKat support (from this source : http://brightechno.com/blog/archives/211). I tested it using my Nexus 4 on KitKat and tested also the fix on 4.3 emulator.
Could you please update the app on PlayStore ?

Thanks.
