feat(scenery): models laid along curves (sweep nodes), bent to follow the paths or repeated along them, loaded and saved with the scenery; trainsets put on a path while the simulation runs; trainset turned around by reversed after its header: the first vehicle stays at the offset and leads towards point 1, the rest stands behind it; launcher keeps reversed trainsets and can turn one around; memory cells saved with the new name of the path they name; events tell their targets and the events of a multiple event; renderer tells whether the cursor is over a surface; vehicle placed in the editor entered when the driving goes on
