crm_uf_get_profile_fields no longer returns 'title' information for fields.

crm_uf_get_profile_fields as of 1.4 alpha returned a 'title' field as part of the associative array for each field in a profile:

$raw_data = crm_uf_get_profile_fields($pid, FALSE, $action, $match_fields);
error_log("Title for first_name is " . $raw_data['first_name']['title']);

This no longer works in 1.4 Beta rek 4915, since while there is still a 'title' member of the array, it is now always null.

This will break several Drupal modules, including volunteer, which relies on this data when displaying UI.
