Now we can change position and rotation for an actor.

I put it to set position and rotation when we press RCTRL, just for test.
I just read a comment from yamashi  stating that "Actor* m_Actor; Should be m_pActor" and then apparently that a_pActor should be apActor which looked like a weird convention. But I'm in no position to criticize your work guys, plus it might be perfectly sensible and I don't know your project enough to say for sure.
