It occurred to me that we aren't really using any of the advanced features of gproc. This PR replaces gproc with the pg module that comes with OTP. Pg is started with the overworld scope to prevent any issues with conflicting scopes for other apps.
This PR changes ECS to only be referred by their PIDs rather than a gproc named process and fixes up some type specs as well.
