Subject: Removed unused camera_position and camera_direction fields from
 Client. Moved ClientEnvironment::drawPostFx to ClientMap::renderPostFx --
 this will make the camera management classes easier to write, as ClientMap
 already knows the camera position but ClientEnvironment doesn't and has to be
 told about it. This also eliminates the need for Client::getEnv(). Made the
 post effect color a content feature defined in content_mapnode.h.
