I put in temporary host-based ramp speed limit, should be optional
In commit #e550ad14 I put in a "temporary hack to control ramp rate in our program instead of firmware." This is because we temporarily had bad microcontroller firmware that would ramp too fast. This "temporary hack" should either be backed out, or (better) made an option that can be selected or deselected. The necessary "if" statements are already in place, it just needs an added gui control someplace.
