Decrease default batch size to max allowed parameters for a single statement (PostgreSQL)

[geofranzi]

If a dataset is updated all original tuples are retrieved based on the tuple IDs.

Core/Components/DLM/BExIS.Dlm.Services/Data/DatasetManager.cs

Line 3086 in 0333967

List<DataTuple> oraginalsOfEditedTuples = dataTupleRepo.Get(p => editedTupleIds.Contains(p.Id)).ToList(); // all the original tuples edited in the current package

If we have more than 65534 PostgreSQL throws an error:

"The PostgreSQL protocol doesn't allow over 65535 parameters for a single statement."

• undo set to 100 000 -> set instead to 65 000 to be on the safe side.
• add comment to warn
