Friendlier on launch

[mccalluc]

Right now we just get an empty screen on launch... Even the grey control bar isn't there on first load.

Perhaps work with Pete and see if there could be a default to bring up a file selector onload if the UI is otherwise empty? Or load tracks as horizontals?

(Probably two distinct issues here: some kind of please-wait during ingest, and some sort of welcome-and-select files once you're in.)

Hmm, if the grey control bar isn't there then the HiGlass client library wasn't loaded. Could you post a screenshot of the console of this happening?

@pkerpedjiev @mccalluc As of #16 the grey control bar is there on first load. I think this can be updated to just be worrying about the "welcome-and-select files once you're in" portion,
