remove tempo end drag (the control drag on the curve). a;ter tempo marker drag.

	- holding down shift before initiating a tempo mark drag
	  alters the end tempo of the previous one as before, but
	  this is now a separate drag.
	- restore vertical dragging of the tempo mark to alter start/
	  end tempo. shift during the makrker drag alters start tempo.
	  xontrol + shift during the drag alters end tempo.
