lots of changes

Added a creation_time field to thinks - using the modified time on the
  filesystem wasn't reliable.

Styled the login page.

The index shows the most recent thinks at the top.

Allow authentication by an Authorization header, with a token specified
in settings.py.

Lots of improvements to the editor, including showing the log, and a
form to install Elm packages when editing .elm files.

The Makefile for a project is automatically run each time a file is saved.
