Added a thick layer og stone so i feels a bit more realistic

Added more ground between the grass and bunker becuse many people requested that.
you can now send bunker busters thru the ground down in to the bunker

Finally a fixed it so you can use the vanilla tools!
Sorry for taking so long to fix this

added som fire extinguishers for more detail and started working on some secret underground tunnels.
