Add public accessor `is_single_entity` to Query
Added accessor :attr:`.Query.is_single_entity` to :class:`.Query`, which
will indicate if the results returned by this :class:`.Query` will be a
list of ORM entities, or a tuple of entities or column expressions.
SQLAlchemy hopes to improve upon the behavior of single entity / tuples in
future releases such that the behavior would be explicit up front, however
this attribute should be helpful with the current behavior. Pull request
