Macro:	ENV - a shortcut for envirionment()

Synopsis:
	mixed ENV

Description:
	'ENV' is a systemwide shortcut for 'environment()' if you hate to
	type that long one. Or even longer: 'environment(this_object())'
	or 'environment(ME)'.
	If not, then it is just the same.  :-P
	
Note:
	It's a simple define: #define ENV environment()

Return value:
	envirionment()
	or 0 if this_object() has no environment
