BATCH adding in TSQLRestServerDB will now perform SQLite3 multi-INSERT statements:
performance boost is from 2x (memory with transaction) to 60x (full locking, w/out transaction)
- I was fed up with the fact that our SQLite3 engine was faster as external DB than as direct DB in BATCH mode, since mORMotDB did incldue multi-INSERT: now the MainEngine outperforms everything... fair enough...
