Don't call conditional_header() if it's defined as being BAD.
Don't call conditional_header() if it's defined as being BAD.

This version should be more AJAX-friendly.  Really, the whole class just needs 
to be completely reworked so it works as it should... not sure if I should do 
that before or after the 1.0 milestone.

/cs_genericPageClass.php:
	* __construct():
		-- ARG CHANGE: NEW ARG: #3: $allowRedir=TRUE
		-- the third argument is stored in a constant, 
		"CS-CONTENT_ALLOW_AUTO_REDIR", which keeps it from being modified.
	* check_login():
		-- added headers after I realized the name of the method is very 
		misleading compared to what it actually does.
		-- calls internal conditional_header() instead of the global one, and 
		exits afterward anyway... this behaviour is questionable at best.
	* conditional_header():
		-- ARG CHANGE: NEW ARG: #2: $exitAfter=TRUE
		-- new argument determines if the method should exit after running.
		-- NOTE: no exit will occur if redirection is turned off, and this 
		behaviour is questionable, at best.
