TkTurf Prompts

To use multi-line prompts:

	TkTurf goes over Turf's head to give you multi-line prompts to use this
	feature just add a "\n" into your prompt configure command.  For
	example, this would give you a two line prompt with your hit points on
	one row, and the room name you are currently in in another:
	
		prompt %h/%H\n%R
	
	This would be a three line showing hp and room on third line:
		
		prompt %h/%H\n\n%R

	Regrettably, it is impossible for TkTurf to use the multi-line prompts
		which Turf provides.  Using them will result in part of the
		prompt appearing in the main text window.
