LP#1839341: Fix boolean save (and other issues)

This commit makes sure that YAOUSen of type 'bool' are saved as JSON
booleans rather than one of the strings "true" or "false".  A database
cleanup script may be useful to make sure that erroneously set values
from earlier iterations of this interface don't stick around and cause
problems.  A simple version of this would be:

UPDATE  actor.org_unit_setting
  SET   value = BTRIM(value,'"')
  WHERE value IS NOT NULL
        AND name IN (
                SELECT  name
                  FROM  config.org_unit_setting_type
                  WHERE datatype ='bool'
        );

Also addressed in this commit are linked field label display (see the
Acquisitions "Default copy location" setting) and a minor low-level call
that requests too-deep object fleshing.
