Fine-tune the import from dictionary tool so that it can import IDMSNTWK
version 1 (release 18.5) without exceptions and with all options
selected.

Note that 1 new area and 1 new record type were added in comparison to
the r16 version of IDMSNTWK version 1 :  DDLDCTRC resp. TRACEREC-177.
The layout manager that was designed for this schema had to be modified
for this reason (location for TRACEREC-177=R1).
