Better looking vines

[bas080]

We want to improve the looks.

The vines at times didn't look good. I have an idea to improve that. Vines should not spawn on the side of spawn nodes.

• They should spawn on-top. They should then grow around the corner and then down. This only applies to vines that grow on sides.

• Even better would be that the vines grow on both ends. This can result in the vine draping over a node.

• Vines should be allowed to spawn on bottom of leaves which looks like they grow from within the leaves.

Bottom growing vines remain as they are.

Much of this has been achieved.

Two issues that are left is either side growing vines which should be made into its own issue.

Another is to define vines that can grow both underneath and ontop.
