Add keyboard shortcut hint overlay that is displayed when a user presses and holds the Super key.

See the attached design "Super_key_shutcuts_overlay.png". The overlay should use exact same border and transparent material as Alt-Tab.

This should be displayed every time the user presses and holds the Super key, at the same time the Launcher keyboard shortcut hints are displayed. Releasing the Super key should hide this overlay, again at the same time the Launcher keyboard shortcust hints are hidden.

Also not that the design of the Launcher keyboard shortcust hints has been updated.

Contact Rosie for all required visual assets and dimensions.
