0.7.0 is from May 2014 and lacks OAuth support and a number of other
updates.

Switch to having Flower use a config file, enable OAuth

Google OAuth requires an additional 4 command line args or environment
variables, so it was time for Flower to get a proper config file.

The broker configuration remains a command line argument because it is
consumed by Celery's configuration parser, not Flower's configuration
parser.

I can't think of a reason our oauth keys need to be world readable

Move templates to live in our new directory layout

Paths under templates/ should mirror their default installation path on
disk to make it easier to correlate deployed files back to source
templates.
