Skylight Calculation of Saline

[Cydhra]

As mentioned in #66 the skylight calculation of the saline MBS does not work, yet.

• [ ] Why does the function for skylight return 0 for all blocks, even when skylight is clearly different at that position
• Fix Saline Blocks being transparent for light
• Replace Zerocore Saline Structure with Our Structure System #71
• Write an update algorithm that schedules checks of skylight calculation for some tiles of some MB structures in the world (so not all structures are updated simultaneously, thus avoiding lag spikes)
• Multiply the skylight multiplier to the base conversion rate of the MBS

Regarding the first point: The problem where the skylight was 0 can actually be fixed by using World#getLightFor and incrementing the y-position by 1.
The problem that remains is that the Saline Wall and Saline Heated Wall blocks do not block light, which leads to incorrect light levels when placing blocks above the structure.
