Fixed LOD pathing issue so LODs work again.

Updated to 0.6

Fixed designations of Hand Axe and Hammer so that this can now be researched again in Survival

Updated texture of gray marble so the dark lines of marbling are less visible. And made color closer to vanilla stone. Hopefully these columns will now blend more cleanly & with less obvious tiling.

Also, please note: You can always flip these and rotate them to mix up the marbling so that the pattern is not repeated. It takes more work but as with most things, may make for an effect you like better.

Massive update for this, adding:

-- Low-poly swap-ins for when you're far away. "LODs" (Levels of Detail) will optimize the play experience, and these will now take up as little as 1/20 the GPU space as before!
-- New Gray version of the large modular column pieces, to match the gray stone of the game
-- Fully Survival-ready, with its own Research tree and blueprints.

I fixed the "Can't Destroy" issue by making these from "LargeStones" instead of "StoneOreSmall." All of the pieces now are destructible and disappear when destroyed, just like they should. Woot!

Minor positioning adjustments for column base, aligns a lot better now.
