Started the v0.9.13 work.
Add texinfo target to docs makefile
Changed Resource.patch_list to respect always_return data.
Update docs/who_uses.rst

Added dbpatterns to who uses
Correct override_urls check in Api (closes #692)

This applies the same change which #516 made to Resource to only issue
the deprecation warning when override_urls() actually returns something.

This also changes the logic in both locations to avoid calling
override_urls() more than once
Handle malformed HTTP Accept values

Some clients cause tastypie to return a 500 error because they send a request
with an HTTP Accept header which contains an invalid MIME type (e.g. any value
without a "/" other than "*", which mimeparse handles).

determine_format() now raises BadRequest any time mimeparse fails.
Resources now handle this by returning HTTP 400 immediately rather than
the normal error response
wrap_view: handle BadRequest exceptions gracefully
PEP-8: replace legacy has_key() with ``foo in bar``
Merge pull request #819 from acdha/692-correct-override_urls-warning

Correct override_urls check in Api (closes #692)

BACKWARDS-INCOMPATIBLE: Format Hardening Release

Format Hardening Security Release

* XML decoding has been wrapped in the defusedxml library
* XML requests may no longer include DTDs by default
* Deserialization will return HTTP 400 for any XML decode errors
* Add `TASTYPIE_DEFAULT_FORMATS` setting to globally restrict the set of
  supported formats (closes #833)
* Content negotiation will return an error for malformed accept headers (closes #832)
* The Api class itself now allows a custom serializer (closes #817)
* The serialization documentation has been upgraded with security advice

Backwards-incompatible changes:

* XML serialization:
    - defusedxml is now required
    - defusedxml requires lxml 3 or later

    ``pip install defusedxml "lxml>=3"``
* Python 2.5 is no longer officially supported because defusedxml requires
  Python 2.6 or later.
fixed authorization if auth function returns False

* added mock to allow easier overwritting of auth
  functions
* tested when authorization *_detail function returns
  False - tests were failing. i.e. request was
  authorized, when it shouldn't have been
* updated code to raise an Unauthorized if *_detail
  functions return False
Fixed typo, should be CleanedDataFormValidation.
Added versiontools support!
Added in rose for simpler versioning.
Bumped to v0.9.13!
