Port the WindowServer and LibGUI to communicate through local sockets.

This is really cool! :^)

Apps currently refuse to start if the WindowServer isn't listening on the
socket in /wsportal. This makes sense, but I guess it would also be nice
to have some sort of "wait for server on startup" mode.

This has performance issues, and I'll work on those, but this stuff seems
to actually work and I'm very happy with that.
