QoL: Show amount of minable resources when placing blueprint

[d4rksh4de]

It would be nice to show which resources and the amount of them when placing blueprint that contains miners.

Why?
When placing single miner it already does show the amount of resources in the area under miner. In case there are multiple ores in the area it shows which resources are there. I use this to adjust miner placement so that it would mine only the needed ore. With single miner it's not that big issue, you can just look on the ground and try to spot other ores that might be in the area. However, blueprints can be bigger and it is not that easy to check the whole area.
