Updated Wagtailsearch settings to use new multi backend search
Removed some accidentally commited code (oops)
Remove redis/celery from default requirements (partial commit of https://github.com/spapas/wagtaildemo/commit/08e3adbcff4ed70b0e552270596a9d676fd624a9)
Changed requirements to a directory

This follows a pattern introduced in two scoops of django in
order to have seperate requirements files for dev / prod. There
is a base.txt requirements files containing the reqs for both
environments and two more requirement files (dev.txt and
production.txt) containing the requirements for dev and prod.

The django-debug-toolbar has been moved to the dev while the
psycopg2, django-celery, gunicorn, redis and django-redis-cache
have been moved to the production.

Also the django-debug-toolbar has been moved to settings/dev.py
and the gunicorn INSTALLD_APP to the settings/prod.py
update vagrant install script to omit redis, and use the new split requirements files
trim down base requirements to exclude wagtail core dependencies (which are brought in via wagtail's setup.py); add psycopg to base
