Tempo Marks : set point colour by discontinuity, display non-quarter pulse if we are non-quarter.

- a jump in tempo by more than 1 ntpm results in a red
	 tempo mark pointer.

	- ignore UIConfiguration::get_allow_non_quarter_pulse()
	  when displaying note type in the marker text (only display
	  note type if we are non-quarter).
