64bit Datatypes not processed

External Datatypes MAXL_DTINT_ULONG64,MAXL_DTEXT_ULONG64 where not processed in _MaxlOutputNextRecord therefore some Values where not given
back.

If you send a display database the following values where affected.
data_cache
file_cache
index_cache
current_data_cache
current_file_cache
current_index_cache

Typo corrected
