Make charming easier

Make charming easier

Update on the assumption that production instances will use a virtualenv.
This requires using "bin/paster" rather than the system paster.

Add an additional deploy_sysdeps make target that installs only the sysdeps
used for deployment, not a mongodb server.

Specify production.ini in scripts/run

Add settings to production.ini:
http_cache was missing, but needed.
Placeholder mongo.host and mongo.port entries make it easier to substitute the
dynamically-determined values in a charm.
