Additional map overlays (dumpable resources , electricity, workers)

Some ideas for additional overlays that would help me a lot:
- Overlays for each dumpable resource to show where they are allowed to be dumped (respects global and mine tower dumping settings to show all dumpable areas for this resource)
- Electricity usage overlay (bar charts over buildings, similar to the mineable resource overlay, but showing electricity usage/production. Maximum bar size could be capped to the biggest currently active consumer/producer, and every other building can be a proportionate size based on that. That should help reduce clutter once usage and production are getting to very high numbers.)
- Worker usage overlay (similar to electricity overlay)
- Overlay to show the dumpable resource composition of terrain (other than the currently available mineable resources). i.e. showing waste, slag, etc - could also be a simple color shading for a single resource to show if a specific tile contains that resource or not.
- Resource stockpiles overlay for storages/buildings
