Ice throw warning sign

In certain circumstances, ice may form on the rotor blades of wind turbines in winter. This can jump off and be hurled hundreds of feet. To draw attention to this danger, "ice throw warning signs" are set up.
This ice throw warning sign is freely placeable and behaves like the standard signs of the LS19.
In the shop it can be found under Placeable under the new category "Windenergy". It costs 100 € in the purchase and 0 € maintenance.
A big thank you goes to Ifko [nator], who allowed me to use the script "AddStoreCategory" !!!
