[Therion] Main route through a cave

[Benedikt Hallinger]

Hi,
We might also differentiate the route finding symbols into two line types: one for the main junctions and one for the route in between. This way we can select if we just want to show the main junctions or all the route.

Is there a way of defining custom symbol groups? This way we might create our own to really hide all the routing symbols at once.
