Listed textures (of woodsoils and trunks) and authors.
Simplified woodsoils.png.
Changed trunks_twig_2.png and trunks_twig_3.png to Neuromancer's
not-centered versions (trunks_twig_1.png not because it's the one in
inventory).
First three twig textures are the old ones again.
All other twig textures are based on Neuromancer's "comboSticks".
Added textures for twigs blocks again.
