Escape quotes in insert statement generation using repr(). It also adds 2 tests with strings containing ' and ".
I know this is not a fully database specific solution but IMHO I think it's better than current situation. At least it works for me :-).
I also changed in test_sql.py make_insert_statement(self) to test_make_insert_statement(self) and fix a method call from _prepare_rows_for_serialization() to to_rows(serialize_dates=True).
