Feature Request: Heatmap of latest activity

[h3ndrik]

I'd like to see where in my world something happened. Where players are actively building or digging.
This would allow active monitoring of destructive behavior or enable players to see where active areas are.

I haven't yet looked into the mapserver code so i'm not really sure how this could be implemented. I'm thinking of something like a heatmap (layer?) where areas with recent activity get a different color/hue. Either depending on how recent those changes were, or depending on the amount of changed blocks. Both could be useful.

Sounds interesting, this might be possible if/when the layer-types are configurable someday
