window: Let the user select multiple files to open.

Browse source 
Uses code that drag and drop already uses. It's kinda ugly because the
file dialog returns a ListModel.

As an added bonus, since the button responds to the action "win.open",
it will also allow open multiple files with the primary menu.
It would be a good idea to change the "Open…" label in the primary menu though.

Closes #191
