[0.17.60] Train tutorials mini issues

[boskid]

Train schedules & train stops:
- locomotive can be decoupled from cargo wagon using "V"
- inserters in loading station can be rotated to unload cargo wagon
- "Set the train to automatic mode" uses old graphics for Automatic-Manual switch
- train can be set to automatic with schedule with two waypoints A and B. After out of fuel tutorial cannot be solved

Advanced rail signals:
- On first building part to allow red trains, just removing rail signals on vertical rails is enough to finish stage

Ghost rail planning:
- This tutorial looks to be out of sync with viewtopic.php?p=421756#p421756 - now you need to hold shift to be in Ghost mode, so this "Press R or Shift + R while ghost planning" is wrong. You need to hold shift to be in ghost planning mode and so you need to rotate counter clockwise, always.

Yea, they're going to get another go-over,

Until then, they are all minor issues
