The indexing into the list of sample SWFs could be incorrect
depending on the order of the JSON data. Now we store the SWF info
directly on the option element for easy access, regardless of order.
This commit adds HTML Opt-Groups separating Games and Animations on the web demo sample dropdown menu. There are also a few tiny styling changes. Mainly the addition of a transition duration to the logo image, as well as changing "max-device-width" to "max-width" on a media query so that the "mobile" view is shown if you scale down the window on desktop browsers.
