Currently Global Waystones look identical to regular waystones.
It'd be nice if one could tell the difference between the two at a glance, especially if #142 is ever added.
Perhaps give them a "mossy" look. If they generate naturally, that means they've been around for a while.

Global Waystones are a different thing from generated ones, global ones are admin-placed and available for every player. I might consider a mossy look for randomly generated ones when #142 is added.
