make new (ramped) tempi indidstiguishable from constant to the novice user.

Browse source 
- stretch drag (using shift on the curve) operates on
	  the true meaning of constant. in other words,
	  the only way you can make a tempo ramped is by adjusting the end
	  tempo (shift drag on the *next* mark). from this point onwards.
	  shift-drag the curve will change the start tempo and ctrl-drag
	  the curve will change the end (needs work). to reset the
	  curve to constant, 'make constant' should simply set the end
	  tempo (unimplemented).
