Is this right?  All views app windows opened by chrome.app.window.create() can
be minimized?

(Also, should you be an owner of this directory? I see you are an owner of the
app_window API.  Feel free to add yourself.)

Yeah, I think that's what we want. It's not how it currently behaves, largely
due to not having a CanMinimize().

That said, I should stick to the CL description and leave behavior unchanged in
this CL.
