Merged sqlobject-is-empty [r=lifeless,stub] [f=612351]

SQLObjectResultSet has a new is_empty method that behaves the same
as ResultSet.is_empty. It should be used in preference to
SQLObjectResultSet.__nonzero__, to ensure that code using the
SQLObject compatibility layer can be easily migrated to pure Storm.

Merged any-strips-order-by [r=al-maisan,therve] [f=608825]

The ResultSet.any and ReferenceSet.any methods strip the ORDER BY
clause, when it's present, as a performance optimization.

Merged result-set-in-subselects [r=bigkevmcd,therve] [f=337494]

A new ResultSet.get_select_expr method returns a Select expression
configured to return a user-defined set of columns, based on the
settings of result set. The primary purpose of this functionality
is to make it easy to convert a result set into a form that can be
used as a subselect.

363. By Jamu Kakar on 2010-07-23

- Added missing entries to NEWS file [trivial].

362. By Jamu Kakar on 2010-07-22

Merged is-empty-strips-order-by [r=bigkevmcd,lifeless] [f=246200]

ResultSet.is_empty strips the ORDER BY clause, if one is present,
before issuing a query. The result is the same but will perform
better in cases where the query would match a large number of rows.

Merge mutable-alive-check-553334 [r=jkakar,salgado] [f=553334]

Add a checkpoint call when an object is updated from the cache with values from
a recent query, to detect changes from mutables correctly, and not issue useless
(or even harmful) updates from other objects.
