• Editing in Custom Query:

- now fields are also identified via the database which the field belongs to in order to allow to select/join/etc. fields coming from different databases and to improve the unambiguity of the field origin
- sped up editing check for fields with no table or database origin (then no "select count(*)" is needed)
