Made it possible to specify origins in access.conf

Without this patch, you cannot specify the origin which defaults to
'ALL' and can only specify the user/group. Adds ability to specify this
association as a hash of users and origins.
Cleanup of Takeshi Larsson's contribution. No functional changes.
