As desktop app?

[mccalluc]

We'd like people to use Refinery, or they should be able to use the command-line... but some folks want a desktop app. This work would go in a new repo:

• First, investigate options for wrapping up code, dependencies, and python binary.
• and figure out deployment: github releases?
• then, add an interstitial UI for selecting files.
• In the first pass, the application still just launches into a web browser.
