.tumblr generation flow

This is a nice .tumblr file generation flow.
One thing that could be improved is how the oauth_verifier is received, one of:
* tumblr API supporting desktop apps like twitter does (callback is them, display verifier for copying into a separate app)
* spinning up a small web server locally, and then setting the callback url to that so that the verifier can be nicely displayed.

But either way - flow feels pretty solid.  check it out and let me know!
