Rotatable end when drag-laying tracks

[elgu]

I was watching the gif where the new track laying is shown. What I noticed was, that you had to drag multiple times to get the desired direction.
If it would be possible to specify in which direction the end should end (much like a spline), more complex pieces of track could be layed in one drag.

Example:
- Start draging at an existing piece of track, that way the beginning direction is specified
- Then drag to the end position, but rotate the track end (that you are holding) using the "R" key until the track continues in the right direction.
- Release the mouse button to place the track or cancel using ESC

That way you could for example drag a turning loop in one step, just holding the drag and rotating, so start and end is at the same position.

Rotating with the "R" key is just like rotating anything else.
Pressing "R" it is done with the left hand and draging is done with the right hand, so this will not be awkward.
I'm not sure, how much efford the algorithm should spent finding a solution that matches the start and end position and direction.

That is pretty much how the rail-planner already works

I think in this case I can surely move this to implemented.
