Added support for ShuttleXpress (and then some)

I will start off by saying "This app is awsome! Thanks!"

Anyway, I have a ShuttleXpress I am now using with ubuntu trusty. Using the comment posted at freecode (http://freecode.com/projects/shuttlepro) I updated some aspects of the shuttle app to 1. work with the Xpress and 2. to automatically start when you plug in your contour device

I am hoping to add some more to it as well. I will be using it in Audacity and will make a config for that available. I would also like to make a deb installer to make the install process smoother. 

Thanks!
