databases/cego: update 2.48.34 -> 2.48.36

• Renaming date function dateformat to scandate to reflect its scanning function. Please note, that cegojdbc uses this function in CegoPreparedStatement class.
• Fix in CegoXPorter for view import. For view creation, the field entries in schema must be setup with a unique id ( analog to view creation via sql command )
