---------------------------------+--------------------
If two Django engines are configured and a template object from the first
engine is used as an include or extends in a template from the second
engine, it's not clear which engine will be used if the template object
also happens to include or extend other templates.

Per discussion with Aymeric, it sounds like the least ambiguous behavior
it to raise an exception if an included or extended template has a
different engine than that of the current template.

This affects the IncludeNode, ExtendsNode, and InclusionNode.
