a small fix for the opening of the transport.

Change and addition to the trading system.
Now you can sell items directly from the inventory of your equipment, if you put it in a radius of 60 meters from the terminal. And most importantly, you can sell the equipment itself!
Changed prices. They have become more acceptable and depend on the category of goods. The most expensive remained transport and design.
Moreover, cars are bought cheaply from players, but freight and fuel cars are much more expensive. Sold equipment disappears and you can not buy it back yet.
In the shopping menu, small icons were added near the items for better perception.
Reduced the radius of the revival at the place of death to 1500 meters.
In the design added retractable ladder for triangular floors with openings.

Added retractable ladder for plates with rectangular openings. When folded, it is locked.

Added 3 new basic frame designs: the floor is triangular, the floor is square and the wall. All other manipulations with them occur through the upgrade menu. For example, you can sheathe their plywood or boards.
Total new designs added 17 pieces. Two more in development.
The configs of old structures were rewritten, which may cause small vertical displacements of the floors and up to 2 meters near the walls.
Recipes crafting and upgrades revised. Almost all recipes have a toolbox, but hammers and a tape measure have been removed. The toolbox itself can be crafted.
Added new material - plywood. Added 2 recipes for crafting nails.
Now you can make 2 boards or 4 sheets of plywood from 1 log.
By this we will save the forest, gentlemen!
Wooden walls and floors are removed from independent craft. Now you can create them only through upgrade frames.

Changed the names of all the child classes static objects inherit from "WC_Construction_Static". Of them removed the end of the "_Static". If you are using construction in your scripts or databases, then remove these endings on their own.
Added new design. They are still not fully functional in the nearest update will be completed and described.
