Status

• IN DEVELOPMENT
• Needs to be added to png loader and loader colors.
• Doesn't work on server when tested in "all mugg PRs merged", I will look for a fix

Description

[added] Solar Panel

This PR adds Solar Panel as a new Source component.

It will provide power based on luminance of SColor fetched via getMap().getColorLight(this.getPosition()).

Light must be above a set threshold otherwise power is 0 and tick frequency is 45. The threshold is set to 140.
If light is above the threshold, then power is (light - LIGHT_THRESHOLD) / (250.0f - LIGHT_THRESHOLD) * power_source and tick frequency is 3.
Therefore, Solar Panel provides power based on the light amount. If there is less light then it will provide less power.

Blob emitted light will work, so a Solar Panel can be powered by a Lamp.
However, there is an issue where blob emitted light will go through walls.
This is partly the reason why I introduced a threshold (see above).

I might change Lamp to give less light if it has less input power.

Does not function correctly on a dedicated server, seems to just output at max power all the time regardless of the brightness
