Major Redesign for new versions of Firefox OS

I've been using this app since I first saw it, but I realized that it was not longer updated.
I can't add really any new feature, but at least I can redesign the interface to be more consistent with the new versions of the OS (1.3+).

So this is my take on the app, feel free to try it and hopefully you'll find it good enough to put it on the Marketplace as an update.
