Bookcase rework/resprite

[McRamon]

What Does This PR Do

1. Reesprites basic wooden bookshelp
2. adds 3 new bookcase types:
   a) metal bookscase - can be crafted with metal
   b) metal NT bookcase - can not be crafted. Will be mapped in (if accepted) into certain locations, such as NT office, CC etc.
   c) military bookcase - can be crafted from plasteel, has more sturdy "military" look. Can also be used later in mapping for locations where it would fit, such as syndicate bases, outposts, etc.
3. reworks bookcase code in a way that books that appear on the sprite when books are placed on hte shelves, are now an overlay.

Why It's Good For The Game

More variety in style of furniture, better sprites than the old ones.

Images of changes

Testing

ran local server, constructed bookcases, deconstructed them, filled them with books to check different overlays working properly.
