Highlight device when selected from the main activity list.

I had to include the style files, made with http://android-holo-colors.com
because, from kitkat on, the background color of highlighted elements is
gray instead of blue, but that's not reflected in the resources included
in the support library v7 appcompat jar, that are still blue.
