[PATCH] Don't add splitted ways in the end of relation

[Teemu Koskinen <teemu.koskinen@…>]

This patch will change the behaviour when splitting ways.

The created ways will be added to the relations the original way is a member of just after the original way, not to the end as it currently does.

If the way is multiple times in one relation, the new ways will also be multiple times in it.

This ensures that the order of the relation as a whole stays the same as before, this is important in route relations.
