Description:
	There seems to be a bug with a compiler when using #emit in files included
	more than once, so this code has been moved to a file only included once.

Version:
	0.2
Changelog:
	03/01/13:
		Added "@foreign" and "@global" for EXPLICIT Master_Caller use.
		Added "void:" return tag to simplify common code.
	07/08/10:
		Split in to y_masteronce.
		Added assembly for publics scanning.
	06/08/10:
		Managed the ultimate - got completely transparent inclusion!
	05/08/10:
		Completed new master system, now does all syncing and clients.
	06/10/09:
		Rewrote using states.
		Added remote function macros.
		Reduced the number of masters to a single one.  It must have them all.
		Vastly simplified the master model - ending the master ends everything.
	06/01/08:
		Added code to not pass data if no other script exists.
	17/11/07:
		Added code for a script to remove itself from the global list.
	11/10/07:
		Not first version but added documentation months late.
