+ Added "Battlegrounds Turf", a faded, war-torn grass with pebbles scattered about.
* (Exists as a ground type for the biome of the same name in Hamlet where the iron hulks are found, but goes unused due to the way worldgen is set up, and thus those spots end up being barren turf instead)
+ Added "Replica Pig Ruins Turf", a version of the Pig Ruins turf that doesn't act as if it's inside the deep jungle (i.e. no canopy shadows or screen border)
* (Already existed in game as a ground used in the Iron Thing set piece, but had no associated turf item.)
+ Finally fixed the inventory images so they show up instead of being invisible.
* There are only two types, though; land and sea. I don't have the patience to make unique icons for each different turf.

Fixed the borders of the carpets. They should now flow seamlessly into real water.

Fixed the lilypond carpet texture to the proper one used in-game by the real lilypond.
