Bug 1005127 - [privacy] Add ability to delete profile

Works fine for me.
It required to add some new mixins, views and unit tests.
Both of these are separate form and have target to different views although they have some fields in common.
I looked more into this but couldn't find a way that could achieve what we want to do here.
@bobsilverberg  Please let me know if you know of any solution for this, I will be happy to make the change.
