Django-autocomplete-light

- ! BC BREAK ! CreateModelField is gone, it didn't work when another field
of the form didn't validate. There isn't a really sane way to create the
option in the form field field. Instead, this is done in the view, like
in DAL v2.
- ! BC BREAK ! dal_tagulous was removed in favor of django-tagging, because
tagulous already provides its implementation of a select2 widget.
- 610 Fixed a rendering issue with multiple selects. Upstream patch
proposed but not merged yet: select2/select24226

3.0.1 573 Updated MANIFEST to include static files.

3.0.0 Rewrite: easier to use, test, maintain and support.

registration to the view like in django-select2 using queryset.query caching
which would resolve that use-case.

It's a pretty big release and I waited a while because I wanted all
contributors to benefit from it and work on the same codebase instead of
privileging one to another, not sure if it was the best way, let me know !
