Comment:
OK, here is my draft patch. I have not tested it thoroughly; there may
still be a few issues to smooth out, so test-drivers would be appreciated.
A few notes:
* Reverse relationships work
* You can now use any field path that search_filters will accept
* I have removed the strict validation in favour of letting
setup_joins catch any issues, as search_fields does. We could perhaps look
at adding admin validation for field paths for both instead.
* I played around with combining multiple limit_choices_to clauses
based on the models in the field path, however discovered that in practise
it really doesn't make sense to apply any before the final model in the
field path
* limit_choices_to is respected for AllValuesFilterSpec, and a utility
function is provided if other filterspecs wish to do likewise
* There are some basic tests included in the patch
