Adds transport drones and transport depots
Mods introducing new content into the game.
Augmented or new ways of transporting materials - belts, inserters, pipes!
Version 0.2.0 is preventing placement of mining depots anywhere on the map with the caution slab remaining (and unremoveable).

I have released a new version of mining drones, it should be okay
