Updated all animations to use 0.6.4 settings.
Fixed minor texture glitches
Reworked collider for the square window so it can be used in boats

Added "Rough Sand" to mechanical milling -- using coarse millstone

Fixed LOD pathing issue so that LODs work again.

Big optimization & quality-of-life update:

-- Fixed reflectivity so panes look much more like actual glass
-- Adjusted intensity of glass coloration to help night-glow
-- Removed a lot of unnecessary code & texture info
-- Smoothed out rivets so they no longer appear blocky

Updated to add both window options (left & right) for the large round wall window openings.

Fixed poor transparency, which was introduced by a Keen update recently.

Updated in-game descriptions of Basic Glass and Rough Sand so it is easier to understand how and where to make these.

Cleared up the names and descriptions of some of the windows so they're more user-friendly.
