Make SAC values in planner settings respect unit settings
So far, the fields for the two SAC rates did not show a unit and were implictly l/min.
Now they respect the settings for volume units. This was harder than I thought for two reasons:
1) Imperial units for SAC are cuft/min but a typical value would be .70. So I made the point
the field prefix and what is entered is actually hundreth of cuft per minute.
2) I had to get the rounding right in order not to get effects like 20l/min become .70 cuft/min (19800 ml/min
internally) which would then become 19l/min when switching back.
While being at it, I gave the gradient factors '%'-signs as units.
