Train disconnect valves position improvment

Speedometer now works!!! Also some position improvements.

removed unused files

Scripts are now updated from ported 2017 to 2018 for E types

improved some systems

The second build, all systems online, train does not start, all metrostroi 2017 files(whole textures, sounds and scripts) are kept for debugging

The first upload of it, nothing works, but I wanted no one to upload it before me, as it's my addon
