Adding is_ground_content = false to all digtrons

I just had a test digtron get mostly destroyed by a dungeon generating
around it as it crossed a map chunk boundary. Apparently dungeon
generation can extend into already-generated map chunks, to prevent
dungeons from getting cut off. Hopefully this will prevent such a
tragedy from happening again.
