Markus Hitter fc70e00ca2 DDA: don't queue up heater waits. 
Not queuing up waits for the heaters in the movement queue removes
some code in performance critical paths. What a luck we just
implemented an alternative M116 functionality with the previous
commit :-)

Performance of the slowest step is decreased a nice 29 clock
cycles and binary size decreased by a whoppy 472 bytes. That's
still 210 bytes less than before implementing the alternative
heater wait.

Best of all, average step time is down some 21 clock cycles, too,
so we increased general stepping performance by no less than 5%.
