[11999.5] Support loading tables with default filling into SQL-Loader

Browse source 
* Add special field markers to fill a column in SQLStorage with default values
* Add a safeguard to DBCStorage::EraseEntry, Add helper function DBCStorage::InsertEntry to store content

Note: If required similar adjustments to DBCStorage might be reasonable if required
