Konami Code Easter Egg to trigger new Media model

[tw2113]

Just a harmless easter egg that will trigger 3.5's media uploader via the post editor page. It'd be a fun touch, imho.

To trigger, just use your keyboard and press, in order, up up down down left right left right B A

js diff on post.js

Ignore original diff file, holding off until after 3.5 and with better js.

revised js for the key tracking

Forgot to comment. Hoping my new diff is cleaner and less of a memory hog over time, especially given how much typing goes on in the screen it was intended for.
