pretty-print config, use latest handbrake-js

Hi, cool app! I have tested this with the latest version of `handbrake-js`, seems to work fine.. although I don't have any DVD files locally so couldn't test the TV show stuff.. 

Why isn't this on npm? I would recommend this to friends.. also, the `buildDVDInformation` output parsing you're doing looks interesting - is it something that could be abstracted into a separate module?
