change_orientation missing

We have the following four assign_ action nodes for movable objects:

• 8.8.2.4 Action assign_position
• 8.8.2.5 Action assign_orientation
• 8.8.2.6 Action assign_speed
• 8.8.2.7 Action assign_acceleration

But we only have three change_ action nodes:

• 8.8.2.11 Action change_position
• 8.8.2.12 Action change_speed
• 8.8.2.14 Action change_acceleration

So we assume the change_orientation was lost in the process.

Stretchgoal: Often, one wants to define only the heading, not all three dimensions. We would prefer a second argument with only heading as input.
