Fix the tempo note-type hallucination.

	- after reports that a tempo with non-4.0 note type
	  would produce a ramp in the preceding section, an incorrect
	  assumption was made leading to a bogus 'fix' that redefined
	  Tempo's pulses_per_minute().
	  the real fix was simple:
	  the ramp's function constant was calculated using the note type
	  of the proceding tempo rather than the current one.

	- this patch reverts e82482e8e9c and a4d67279e0086258
	  and maintains the old definition of Tempo::pulses_per_minute()
