The following endpoints are supported:

- POST /drafts
  Description: creates or updates a draft
  Accept: application/x-www-form-urlencoded
  Params: see grapho.DraftPostCommand

- GET /drafts
  Description: lists all drafts as json

This is just a rough prototype to connect all the pieces.  Proper HTML
and JSON rendering needs to be implemented.
