create_engine() flag when using the pyodbc
dialect. Previously this flag would be
ignored if set to False. When set to False,
you'll get "SELECT @@identity" after each
INSERT to get at the last inserted ID,
for those tables which have "implicit_returning"
set to False.
- [bug] Removed warning when Index is created
with no columns; while this might not be what
the user intended, it is a valid use case
as an Index could be a placeholder for just an
index of a certain name.

- [feature] Added interim create_engine flag

to force whether or not the dialect
passes Python unicode literals to PyODBC
or not.

rendering of SELECT statements with aliases

for the benefit of the test.lib.schema package.
- use test.lib.schema.Table for the table within test.lib.fixtures.DeclarativeMappedTest
- [bug] Removed the check for number of
rows affected when doing a multi-delete
against mapped objects. If an ON DELETE
CASCADE exists between two rows, we can't
get an accurate rowcount from the DBAPI;
this particular count is not supported
on most DBAPIs in any case, MySQLdb
is the notable case where it is.

from the Core (see below). [ticket:1859]
- [feature] Added support for SQL standard
common table expressions (CTE), allowing
SELECT objects as the CTE source (DML
not yet supported). This is invoked via
the cte() method on any select() construct.
