Migrate all ACLs from old SMS -> new

Created by: msb

Move all old SMS to the new model done in #5 (closed). The old SMS uses ACLs with mixed crsid, group_id, and inst_id. We need to move all of this to the new model. We also want to the new model the current visibility list:

    # -- Visibility - who is allowed to see the video.
    # -- world - media item is world visible unless restricted by acl
    # -- cam   - media item is cam visible unless restricted by acl
    # -- world-overrule - media item is world visible regardless of acl
    # -- cam-overrule   - media item is cam   visible regardless of acl
    # -- acl-overrule   - media item is restricted by its acl field regardless of acl****
