WindowServer+LibGUI: Make client/server greeting faster

Browse source 
Instead of doing a full IPC round-trip for the client and server to
greet each other upon connecting, the server now automatically sends
a "fast_greet" message when a client connects.

The client simply waits for that message to arrive before proceeding.
(Waiting is necessary since LibGUI relies on the palette information
included in the greeting.)
