Title: Fix issue #154: No way to logout or back to home (root site) page from any page.

Simple solution for add external links as logout or back home page.
I can't fix it by `MenuItem` because it has more difficult logic.
This implementation doesn't have `is_accessible` checking, probably better add it (for example logged user and anonymous must see different representation for logout link).
