	setup TeamTalk and other popup windows
	
	Usage:
	use URL in href attribute, and expand class attribute with the following values:
	sN_STR			_STR = name for popup
	bS_NUM			_NUM = 1 or 0, scrolling on/off
	nW_NUM			_NUM = popup width in pixels
	nH_NUM			_NUM = popup height in pixels
	
	bR2W_NUM		_NUM = 1 or 0, is ratio to width used true/false
	nRW_NUM			_NUM = 0 to 1, number to multiply width
	nRH_NUM			_NUM = 0 to 1, number to mulitply height
