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. Signed-off-by: Robert C. Helling <helling@atdotde.de> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
