Minor tweaks to the UI and data model to better support instance awareness and manageability. The Oracle code is WAY out of date and, not having an Oracle install, I'm not going to worry about it now. Version bumped to 0.9.5b and I removed Simon from owner list as he's no longer active in the community. Release will be tagged oacs-5-1-compat but work will need to be done to get it going on oacs-5-2.
change ad_verify_and_get_user_id to ad_conn user_id, change ad_maybe_redirect_for_registration to auth::require_login, make some db_ and dt_ function -public
