Development server.

This server is intended for development only: it enables debugging tools,
and use a different port (5000) so it can more easily interface with other
applications.

Launching the server is relatively easy::

    $ make dev

    # display an interactive debugger in the browser for uncaught exceptions, which
    # overrides custom error handlers like @app.errorhandler(500). To test how uncaught
    # exceptions are handled by custom error handlers in a production-like environment,
    # set debug=False.
