Maintain a reference to the parent/root serializer

Allow views to specify what template to use

Added @max-arnold, @ralphje.
Thanks folks!

Modify 415 error content

add View.head() method at runtime (issue #228)

support utf8 description

add_query_param should preserve previous querystring

Modify mixins.py to make sure that the 415 (Unsupported Media Type) returns its error in the 'detail' key instead of in the 'error' key (for consistency with all other errors).

Implements Accept headers from IE in the case describe in Issue 215

Patch to enable Accept headers in Internet Explorer when an Ajax Library on the client (i.e. jQuery) is sending an XMLHttpRequest

Pass request to related serializers

Related serializers may need access to the request to properly serialize
a child resource.  For example, reverse() in djangorestframework.reverse
uses request if available to return an absolute URL.  While the parent
resource has access to the request to generate the absolute URL, the
child resource does not.

Small patch to allow RawQuerySet serialization
