 Bug 11807 : Add support for categorycode conversions when updating an user using a LDAP server.

To test

1/ Apply both patches

2/ This patch lets you easily configure mappings for categorycode values.
These mapping will be used when updating the user's account after a successful LDAP login.

Here is an example configuration :

<config>
  <ldapserver id="ldapserver>
    <mapping>
      <categorycode is="usertype">STU</categorycode>
      ...
    </mapping>

    <categorycode_mapping>
      <categorycode value="STU">STUDENT</categorycode>
      <categorycode value="EMP">EMPLOYEE</categorycode>
    </categorycode_mapping>
  </ldapserver>
</config>

3/ With this configuration, LDAP users with the usertype value "EMP" on the LDAP server should have the "EMPLOYEE" categorycode in Koha.
