Moved CPrimaryScreen and CSecondaryScreen to the lib/synergy
and the platform specific implementations to lib/platform. Added an lib/arch method to query the platform's native wide character encoding and changed CUnicode to use it. All platform dependent code is now in lib/arch, lib/platform, and the programs under cmd. Also added more documentation.
