Add Django 1.5, 1.6 support

This avoids statictemplate not producing output in the event that the
user has a middleware that requires login for all pages, for example.
Use contextlib.nested instead of nested with statements
Add clarification on response code exception text
Add test for meddling middleware
bumped version
Added language and extra_request arguments (documented in README)

Make override_middleware optional
