integrate custom-field search in token processing

Browse Source 
to allow to use something like: "<regluar-match-token> +<custom-field-match-token>" to return correct entries matching both
also no longer search private custom-fields not accessible by current user (gives a slower query, if private cfs exist)

* Return criteria array for a given search pattern
* Return SQL fragment to search custom-fields for given $pattern
*
* Reimplemented to handle search in custom-fields by ORing with a sub-query
* returning all auto-ids of custom-fields matching the search-criteria
* To be or-ed to query for $_pattern in regular columns of main-table.
*
* @param string $_pattern search pattern incl. * or ? as wildcard, if no wildcards used we append and prepend one!
* @param string &$wildcard ='' on return wildcard char to use, if pattern does not already contain wildcards!
* @param string &$op ='AND' on return boolean operation to use, if pattern does not start with ! we use OR else AND
* @param string $extra_col =null extra column to search
* @param array $search_cols =array() List of columns to search. If not provided, all columns in $this->db_cols will be considered
* @return array or column => value pairs
* @return string with SQL fragment running on main table: "id IN (SELECT id FROM extra-table WHERE extra_value like '$pattern')"
