LibGUI: Add a simple "recently open files" feature

This feature allows any application to easily install an automatically
updating list of recently open files in a GUI::Menu.

There are three main pieces to this mechanism:

- GUI::Application::set_config_domain(domain): This must be called
  before using the recent files feature. It informs the Application
  object about which config domain to find the relevant RecentFiles
  list under.

- GUI::Menu::add_recently_open_files(callback): This inserts the list
  in a menu. A callback must be provided to handle actually opening
  the recent file in some application-specific way.

- GUI::Application::set_most_recently_open_file(path): This updates
  the list of recently open files, both in the configuration files,
  and in the GUI menu.
