Added the maps for the four U8 maps: Blockade Buster, Summerfield, Undermine, Siegebreaker.
The mine hatches or whatever they are called are not added on the Blockade Buster map, there are 24 of them and they will just crowd the map if I add them. And it's not like they are hard to spot anyway.
The minefield from the Undermine quest is not marked either, I wasn't in the mood to recreate it pixel by pixel. I will probably color that whole cavern green later and be done with it.
