ANNABURGER XM3 NF-MARSCH EDITION

Here is the extended version of the manure spreader for the NF marsh, which can also spread compost on the field.
I created a separate mod for this because if I integrate it into my Holmer pack, everyone else not playing on the NF march will get warnings about missing filltypes, which is what I want to avoid.
Otherwise there isn't much to report.
