Autodrive Course for Ellerbach 1.4 v0.8 Beta

Since there were no autodrive courses for the Ellerbach card yet, I started with it

Version 0.8 beta
- several small changes based on suggestions for improvement
- Added field edge rates for a few fields ... (more to come)

Beta because not fully retracted ...
only connected a few productions so far
Trunk lines almost completely
the further progress comes in the course of the "Corona period" :-)
