Initial commit (libGDX core, desktop, and android)

* Please update your Eclipse + Android SDK version to the latest you can
get (and your JDK, if you haven't in a long enough while).

* You may get errors for the android version of the project. If so,
select it and press "ALT-ENTER". On the left-hand side you'll see
"Android" as one of the categories. Within that pane, you need to select
Android 4.4.2 (the latest version).
