A sell point accepting everything, crops, production pallets, bales and wood.
Usefull when space is lacking.
Added selling of Wood Containers.
Added support for missing Higlands & Fishing products (Young Trouts and Salmons), and moved COAL into a STORE category so it can be sold.
Fixed terrain leveling, painting and clearing areas.
Rewritten store categories, now should accept any extra crops and products added by mod maps, if accordingly prepared.
To avoid errors, i've added a very small price to snow and road salt.
