Don't save actdim="{0,1}" for state{less,ful} actuators, respectively.

Browse Source 
actdim has a default value of -1 (==unset), which means it currently gets saved for all actuators. After this change, it will only be saved if the value is > 1, errors are thrown for stateful actuators with actdim=0 and stateless actuators with actdim>0.
