Add dynamic selection of tree texture based on season and snow level.
...
All tree texture sheets now contain 4 different texture sets for
different conditions. See Docs/README.materials for details.
Also retire the -summer and -winter variants of tree textures, which
are now redundant.

Correct atmospheric scattering for trees, where we were applying ambient lighting twice, making them too dark, and not using an alpha test.
...
Also fix the tropical trees, where only half the texture was defined.
