feat: Implement "point towards random direction"

Browse source 
We subtract 180 even though the value will be clamped, for clarity. We round so that
using the "direction" getter will yield a sensible result. Note that this
implements 'point towards random direction', not 'point towards random
position' -- they have slightly different behaviours.
