Fixed #21029: Test for previously-commited SchemaEditor.__exit__ bug.
Project/ModelState now correctly serialize multi-model inheritance
Also test failure case of ProjectState dependency resolution
Fixed awkward indentation in admin URLconfs
Added AdminSite attributes for easily changing admin title.
AdminSite now has overridable site_header, site_title and index_title attributes. Changed
each admin view to pass these to the context (in a new AdminSite.each_context() method).
The intent here is to make it easier to override these things in the common case, instead of
having to override a template, which is a bigger burden.
Migration autodetector now corerctly deals with proxy models
Consolidated documentation for F() and Q()
Merge pull request #1544 from evildmp/ticket_20920_rebase

Fixed #20920 -- Consolidated F() and Q() documentation
Fixed instructions for running a subset of tests.
Fixed #11857 -- Added missing 'closed' property on TemporaryFile class.

- TemporaryFile now minimally mocks the API of the Python standard
  library class tempfile.NamedTemporaryFile to avoid AttributeError
  exceptions.
- The symbol django.core.files.NamedTemporaryFile is actually assigned
  as a different class on different operating systems.
- The bug only occurred if Django is running on Windows, hence why it
  was hard to diagnose.
