LibGUI: Revert GWindowServerConnection to being a singleton

Browse source 
This was a mistake, of course. Nested event loops don't need (or want)
independent server connections.

We initialize the connection early in GEventLoop for e.g. users that
want to get the size of a GDesktop before the connection has been
established.

Bug noticed by Andreas, introduced by me ;-)
