fix(dashboard): scenery models keep their colors, lit like the game

Browse Source 
Glom models (multishader) drew their trees, rocks, fences and water white.
Their conversions kept on disk from before meshes carried their multishader
tag were still served (the cache format version was never bumped), so every
part fell back to the LEGO shader, whose texture alpha lays the (mostly grey)
texture over the vertex colors that hold the actual colors. Browsers also
kept those models for a week.

- Bump the conversion format so old conversions are made again, and put it
  in the manifests; the viewers add it to model and texture URLs.
- Light scenery as the client's shaders do: the scene's sun and ambient
  light from its .lvl (read as level_read_lighting_info, 0x0102f8f0, and
  EnvironmentManager::SetLightEnv, 0x01088aa0, do), per vertex, clamped,
  instead of the view's own lights, environment map and tone mapping. The
  zone takes the lighting most of its objects' scenes have.
- Programmable shaders read vertex colors and ignore NiMaterialProperty's
  color and alpha; unlit and untextured shaders (by mapShaders gameValue)
  leave out lighting or the texture. Fixed function stays as it was.
