unicode support on admin delete

[Ricardo]

Having the admin app in other language (portuguese, btw) and while trying to delete a record holding non-ascii characters it fails with:

'ascii' codec can't encode character u'\x??' in position ?: ordinal not in range(128)

I replaced contrib.admin.options.py, in delete_view()

if request.POST: # The user has already confirmed the deletion.
  if perms_needed:
     raise PermissionDenied
     obj_display = str(obj)
     obj.delete()

with

if request.POST: # The user has already confirmed the deletion.
  if perms_needed:
     raise PermissionDenied
     obj_display = u"%s" % obj
     obj.delete()

looks ok.

I hold revision 8600 but diff'd against 9000 (haven't had time to sort django-multilingual difference)

A possible fix using force_unicode()

(In [9070]) Fixed #9129 -- Restored a force_unicode that was lost when unicode changes were merged to newforms-admin. Thanks Ricardo & Ramiro.
