LibGUI+WindowServer: Add new WMEvent Super+Space

To make Assistant useful we need a way to quickly trigger it. I've
added a new specialized event coming from the window server for when a
user is holding down 'Super' and hits 'Space'.

The Taskbar will be able to listen for this event and spawn a new
instance of the Assistant if it's not already running.
