It would be nice for everyone, if the NativeWindow apis could be used without needing a window object. As a start (along with other refactoring work for quick share in context menus), I want to move NativeWindow.contextmenus to a jsm. We can provide a shim in browser.js so that everything there continues to work as normal.

This is a straight move. Fennec won't work with this. We'll have to fold it with patch 2 when landing.

This fixes things up so that context menus continue to work like normal.
