[0.15.1]Rail remnants don't have ends, stone of rail ends ov

[y.petremann]

As seen in the image bellow, we can see that:

1. Rail remnants don't have stone part of rail endings, thus making the rail stopping like in old versions.
2. Rail ending stone part overlap over rail remnants

My proposed solution would be to separate the stone part of rail endings from rail endings and to add it to every rail ending not connected to any type of rails (remnants or not), the "functionnal part" of rail endings should be kept like now.

I don't consider this worth the time to change.

The "rail ends" are pure visual and not actually part of the rail.
