 RETURNING support

-Firebird 2.0 supports returning a result set from inserts, and 2.1 extends
-that to deletes and updates.
+Firebird 2.0 supports returning a result set from inserts, and 2.1
+extends that to deletes and updates. This is generically exposed by
+the SQLAlchemy ``returning()`` method, such as::
 
-To use this pass the column/expression list to the ``firebird_returning``
-parameter when creating the queries::
+    # INSERT..RETURNING
+    result = table.insert().returning(table.c.col1, table.c.col2).\
+                   values(name='foo')
+    print result.fetchall()
 
-  raises = tbl.update(empl.c.sales > 100, values=dict(salary=empl.c.salary * 1.1),
-                      firebird_returning=[empl.c.id, empl.c.salary]).execute().fetchall()
+    # UPDATE..RETURNING
+    raises = empl.update().returning(empl.c.id, empl.c.salary).\
+                  where(empl.c.sales>100).\
+                  values(dict(salary=empl.c.salary * 1.1))
