Subject: LibDesktop: Switch to LaunchServer for DesktopServices::open

Moves DirectoryServices out of LibCore (because we need to link with
LibIPC), renames it Desktop::Launcher (because Desktop::DesktopServices
doesn't scan right) and ports it to use the LaunchServer which is now
responsible for starting programs for a file.
