Changed how the Mounted Sun Lamp inherits its data now so that it may be better compatible with 24h grow period mods.

- The chandelier had a missing description. It now has one
- Also, the chandelier has been given a beauty score. Was 0, now 4.

Small XML update to conform to updates made in Perspective: Buildings

Added a mod option allowing players to turn off the visibility toggle button, if you don't use it and don't want the extra icon clutter down there.

Performance update
- Spent some time fine tuning the custom graphic drawer that the chandelier uses for its flames, improving performance by 30%.
- The ceiling fixture toggle button now remembers its settings between game sessions.
- Fixed the chandelier's offsets that got messed up in the previous update.

Small update
- If you use Perspective: Buildings, all 1x1 ceiling fixtures now have 8-way half-tile offsets, so that you can center 1x1 fixture in an even-tiled space.
