Add "Acceleration" and "Maxiumum Speed" to Basic configuration tab

[klues]

The tab "Basic configuration" currently does not have the possibility to set the "acceleration" (AT AC, [0-100]) or the "maximum speed" (AT MS, [0-100]).

There should be two additional sliders in the Tab "Basic configuration". However it possibly makes sense to hide them by default and only show them by link (like "x/y" separation now), because most of the users will not need to change these values.
