Keyboard Navigation

Added some really simple keyboard navigation to the new photoblog, with a little legend that reveals itself when you hover over the Back to Top button – I feel like that's an appropriate time to be like, "Hey, guess what? You could navigate this way, too." I'm sure not everyone will find it, but maybe that will make it feel a little special for those that do.
