A new construction skill - Ancient Architecture

[FrestStar]

Make the 4th level of the construction skill the construction of ancient structures, which opens up the opportunity to create tiles, decor and doors in the style of ruins, as for me it will give a great opportunity for the player to interact with the world and equip the ruins in a single style. Personally, I like to use the potential of randomly scattered ruins on the map as fragments of my base, and if you repair them using the current set of tools (standard tiles), then due to the difference in style it does not look as beautiful as you would like. If a level 4 skill seems pointless for such a thing, then you can just use the option of the ruin version as a skin for tiles.
