Confusingly, the `Source` base class has methods for `get_parent`, but
they were never put to use, I think David has explained why. It's not
ideal, but the object model in kupfer is simple, too simple. Objects
don't have a home, and file browsing is just like browsing other kinds
of collections (recent documents). Unfortunately this means that ←
more often works like erase than go up.

One thing we can do with kupfer right now is to add "Go Up"/"Get
Parent Folder" for any file object. There's no nice way to bind that
to a hotkey, but generic action hotkeys would be nice (Alt + something
performs action on selected object, Alt + ← would be a given for
parent folder.)
