[Rseding91] [0.17.52] Rail cannot be give a fast_replace_group without disabling the ability to cross rails

[Earendel]

If straight-rail is given a fast_replace_group then if you try to place overlapping rail with different directions the new rail replaces the old rail.

For example: You have straight horizontal rail, if you try and place vertical rail that crosses the line it removes a square of horizontal rail and breaks the track.

Ideally the fast-replace action would not trigger for rail if the placed direction is different.

Thanks for the report. It's now fixed for the next version of 0.17.
