Screen Width vs Window Width

[mlavin]

Currently the JS uses the screen.width which assumes that the user is browsing at full screen. Really this needs to capture the current window width since that's what the media queries will use.

I think it would make sense to add window.innerWidth and .innerHeight to the device info as well, in addition to the screen size. Happy to propose a patch if you are interesting in committing it.
