Closes #217

Now it’s possible to use a different static url & root on deploy
stacks.  The deploy static must have BOTH STATIC_URL and STATIC_ROOT
and the static root must be within
“/home/gbeadmin/webapps/gbeteststatic” because the server is configured
to use this directory and only this directory for it’s static file
storage.

Fixed on /demo… I will write up instructions… someday for others, but
for now, reference the demo stack’s local configuration.
