DB4 & Postponed processing

    - New DB4 database type
    - Postponed processing in external module
	+ User may allow external module to finish required processing before
	termination. This could be useful for translation services while using
	console applications (if network connection is slow, the external will 
	never finish translation before program termination)
    - SKIP_PARRENT options are renamed to SKIP_PARENT
