Devlog 54: Pretty lit mountainside base powered by solar batteries

Added batteries to store solar power. We can now power our base at night. They come in small, medium and large capacities at 2, 10 and 50 kWh respectively. More than sufficient to light up the base for the whole night.

Also added 3000K spotlights for that cosy warm white ambience. They are individually adjustable which allows for pretty directional lighting highlights.

You can now adjust the cable slack with mouse wheel for neater cable management. Especially useful for short routing otherwise it will just be hanging everywhere in a big mess.

Most of the work done over the past few months has been in the save/load system. So visually there is not much to show except that it has allowed more complex base builds without having to start from scratch each time. This mountainside base took hours to build with all the cabling and lights. In the actual game, you can probably get by with a smaller simpler base. Of course you can go all out and build a huge base if you want.
