PFAHandler:

- build_select_query(): add support for $search['_'] (searching if one
  of the $this->searchfields contains the search text)
- getList(): make sure '_' is kept in the search parameters

functions.inc.php:
- db_where_clause(): slightly relax checks - if $condition is empty,
  only error out if $additional_raw_where is also empty
