CiviCRM CCK Contact Reference module is hardcoded to only search for 'Individual' contacts - patched to give more options

as mentioned here:

http://forum.civicrm.org/index.php?topic=8468.0#msg37082

...and elsewhere, the CiviCRM CCK Contact Reference drupal module (CiviCRM 3.1.5) contains some SQL which searches for CiviCRM contacts which includes this in the where clause:

WHERE contact_type LIKE 'Individual'

...a patch is attached which replaces this with a configurable option on each CCK field created with this module to specify which contact_types should be included when searching.

e.g. CiviCRM contact_type:
[] Individual
[] Household
[] Organisation

This has had some basic testing using the different widget types provided by the module.
