[INACTIVE] Allow easy negative testing of array index inclusion

    This patch provides the composite operator "! in" (for "not in"), which
    can be used in array tests. This allows the current negative test
	    if (!(index in theArray)) ...
    to be written
	    if (index !in theArray) ...

    The Enhancements to NEdit macro parsing patch includes this small change.
