Fixes message display after action handling.

Calls unicode to force encoding of object name to a localized
unicode string. Also fixes deleted object count by saving
len(queryset) to a local var before calling queryset.delete(), as
the len after queryset.delete() is always zero.

Initial stab at breadcrumbs

There's currently a lot of copy-pasting of breadcrumbs, this can be revisited once we have a better understanding of how we're going to handle navigation.

I've also tried to make template context variables more logical and consistent throughout.
Remove 'python -c'

You should have either `python -c` or '>>>', but not both.  I'm not sure whether "$ python -c 'import this'" or '>>> import this' is better, but the current version is definitely wrong.
