(water is now blue like it used to be)

use soft overlays for cover trim,

(get rid of redundant overlay polys)

before param2 coloring went in.

The intention of this is to fix books in peoples' inventories that are
now inaccessible.  They can be placed, viewed, edited like normal now.

Side effect: all books that were already in-world and that have already
been converted to the param2 colorization before will be grey now, and
most will end up turned some wierd direction, but that can be fixed with
the screwdriver.

If you need to re-color one of the now-grey books, you'll need to craft
one of the desired color, place it, and copy and paste your text from
the grey book.

Newly-placed colored books will behave normally.

- 'setting_get' with 'settings:get'
- 'setting_getbool' with 'settings:get_bool'

also got rid of the old, obsolete "placeholder" node, aliased it to air.
