Discussion: I had problems with sb_min_speed. Web-Interface said it was 3. My debug printf said it was 0. I re-entered -> no effect. I tried to change float sb_min_speed = 3; -> it worked. I tried to change to 0.0, it kept fixed. I returned to 0 -> still worked. Hmmm.

Anyway, perhaps it's a good idea to cast float to int and int to float while setting / reading preferences. This does not fixed above described problem, but I think it makes things cleaner.
