Apply patch from Warren Layton to make the existing default group permission map entries explicit

Now, I have no idea what the base permission setup should look like
for the average library. However, figuring out what permissions are
currently being applied is difficult with lines such as:

  INSERT INTO permission.grp_perm_map VALUES (57, 2, 15, 0, false);

...when it could be rewritten as:

  -- Add basic patron permissions to the Patrons group
  INSERT INTO permission.grp_perm_map (grp, perm, depth, grantable)
VALUES (2, (SELECT id FROM permission.perm_list WHERE code =
'RENEW_CIRC'), 0, false);

To me, this patch makes it very clear which permissions are assigned
to which groups (the permissions for the Acquisition groups are
currently set in this way, too). This added clarity may help when
someone more knowledgeable than me tries to figure out what the "base
permission setup" should be for each group.
