Macro:	NEMESIS - a selector for compiling on different MUDs

Synopsis:
	status NEMESIS

Description:
	'NEMESIS' is defined systemwide for checking if this is Nemesis.
	This can be used by code that compiles differently on different muds,
	like this:

#if defined(NEMESIS) || defined(NEMTEST) || defined(CHATLAND)
	write("You are in a Noah's Ark Corp. MUD!\n");
#else
	write("I don't think we have a Noah's Ark Corp MUD here...\n");
#endif

Note:
	It's a simple define in auto.h: #define NEMESIS
	In NemTest NEMESIS is NOT defined but NEMTEST !

Return value:
	true in Nemesis
