- Rewrote XML patches to improve load efficiency slightly.

- Sand piles no longer deteriorate if outside.

- ... And now, pawns will actually *use* the rock mill. (I'd forgotten to add the relevant WorkGiver to the mod yesterday.)

- Rock mills are now minifiable and movable, and benefit from tool cabinets.

- Added the rock mill (and relevant recipes) from "Fertile Fields" to this mod. This will allow more efficient creation of crushed rocks and sand.

- It's now possible to create concrete and concrete blocks at a rock mill, faster and more efficiently than at a stonecutting table.

- Added patches so that glass from "Glass+Lights" and "Dub's Skylights" is actually made from sand.

- Fixed the concrete and cement graphics so they have black borders like all other items.

- Embrasures now have slightly higher resource costs than do normal walls.

- The market value of concrete "cinder" blocks has been cut roughly in half, to the value of regular stone blocks.

- The market value of concrete has been cut to 2.5, a third of its previous value.

- Fixed a minor problem with drops from deconstructed deep bridges, which had snuck into the mod in the upgrade from b19 to 1.0.

- Clarified in the descriptions of embrasures that they act essentially as permanently-open vents, equalizing temperatures on both sides of a wall.

- Updated to RimWorld 1.0 release!

- Updated some of the mod's graphics (primarily to utilize StackCounts).
