ORM enhanced for BATCH insert

We just committed some nice features to the ORM kernel, and SynDB* classes of our mORMot framework.
During BATCH insertion, the ORM is able to generate some optimized SQL statements, depending on the target database, to send several rows of data at once.
It induces a noticeable speed increase when saving several objects into an external database.

This feature is available for SQlite3 (3.7.11 and later), MySQL, PostgreSQL, MS SQL Server (2008 and up), Oracle, Firebird and NexusDB.
Since it is working at SQL level, it is available for all supported access libraries, e.g. ODBC, OleDB, Zeos/ZDBC, UniDAC, FireDAC.
It means that even properties not implementing array binding (like OleDB, Zeos or UniDAC) are able to have a huge boost at data insertion, ready to compete with the (until now) more optimized libraries.
