Subject: [PATCH] django: Do not check ALLOWED_HOSTS for dummy requests.

Bypass check against ALLOWED_HOSTS for requests with the attribute
is_dummy set to a true value.

This can be used applications which create request themselfs to be
handled by django. It is used by wagtail to implement preview.
