More flexible, less error-prone configuration system.

WARNING: make a backup copy of your local config.py before pulling
this change, as Git will overwrite it without warning.

The configuration defaults to deployment settings, allowing overrides.
Overrides are read from config_local.py and from the file pointed to
by the PILLAR_CONFIG env var.
