Ability to specify additional directories that should have policy files automatically added to inputs when services_autorun is defined

Currently, when services_autorun is defined, policy files (*.cf) from services/autorun are automatically added to inputs. Sometimes I have different desires when it comes to where I want to place policy.

For example, I might want to pickup policy files that are not distributed with the policy set, e.g. /var/cfengine/local_inputs (yeah, that's a bit dangerous).Or I might simply want to have different orginization of my autorun policy, e.g. services/autorun/Service1.

I would like to be able to define a list of the additional directories to automatically load policy files to inputs from.
