Allow Rotation of entity ghosts

[blueblue]

Allow players to rotate ghosts that are already placed using the R and Shift + R keys. This is probably an easy change to make and it makes it way less spooky to work with ghosts, I find myself in need of this feature often when I'm remotely laying belt for example. As an additional suggestion, allow to change direction of underground belt ghosts and flip ghosts via CTRL+R.

I'm for your suggestion though you lost me at making ghosts less spooky, I cannot in good conscience approve of that part.

Agreed. The more ghosts present in a factory, the more haunted the factory should be. As haunting increases, random effects should begin to occur around the affected area(s).
