bump to bugfix alpha version
Bump versions to allow all versions to install

Each component should specify a minimum version and/or any versions that
it is known *not* to work with.  Pinning to minor versions should happen
at the requirements.txt or main Armstrong `setup.py` file.
Add tentative support for Django 1.4
Update TravisCI configuration
Fix requirements files
Update to correct armstrong.dev package for multi-version testing
Add missing apps (Django 1.4 complains)
Make sure that the AuthorsField works in both 1.3.1 and 1.4
Add missing SITE_ID from fabfile (blows up in some systems)
Move Django install to the end

This is necessary in case some other component explicitly requires a
different version of Django.
Fix typo
Switch to < comparison (thanks @niran)
Revert back to old style and then set attributes manually

This feels bad, like the previous iteration, but it is a smaller change
that ensures the object ends up the way we think it should.
Make sure that the MANIFEST.in file is always available
Update to support Django 1.4 (v1.3.1)
Update to fixed version of armstrong.core.arm_sections (v1.3.2)
Merge tag 'v1.3.1'
Merge tag 'v1.3.2'
Update to support Django 1.4.3

This changes more than the requirements because Django had a backwards
incompatible change in commit [37c87b78][].  The new code does not allow
the implicit `through` value to work like it did, so we have to
explicitly set it when creating the manager.

Make sure we continue to support Django 1.3.x
