Added the scripts and config files to run uwsgi instead of pserve
for development.
This fixes a problem that caused pserve to hang up forever when
several ajax requests were sent to generate screenshots of workout
maps (pserve does not handle concurrent requests very well).
After pulled this change, you can start the app manually using the
uwsgi_start helper::
./bin/uwsgi_start development
Or just use the ./bin/start script, which takes care also of starting
ZEO and several other steps.
