Import and render tree models.

Trees are loaded from the new trees.blend using assimp. Tree objects are
then received from the server and rendered on the given terrain
locations.

Each chunk now holds a list of objects and coordinates, which can be
used to easily add other models as well.

Also moded the GLSL fog code to its own shader which can be linked in
different programs.
