The FilePicker has implemented its common locations tray as a composite widget built from a GUI::Frame with a bunch of GUI::Button inside it. The problem with that is that it creates a long and annoying chain of keyboard-focusable widgets. This patch adds GUI::Tray, which is a dedicated single widget that implements the same UI element, but without child widgets.
