Initial implementation of commerical fertilizer, fertilizer bombs and improvements to fertilizing
Modular guns-the guns

Because the only thing better than magic rechambering kits is a magic
base platform that can be repurposed via the crating interface.

This is the first pass; it's based on the SCAR-L.  Feel free to comment
if something looks out/whack, please.
Modular guns-recipe concept

The idea is that you can re-configure the gun by swapping out parts, but
that swap is time-consuming and requires both skill and the proper
equipment to get right.  The guns are pretty good but not perfect, and
can't be tacticool'd out.

Numbers here are not set in stone and frankly I've not cross-checked
them because I'm thinking they're likely to be changed as firearm fans
check in.  So let me know what you think of the details, please.

Tweak
Tweak2
Recalculate the coverage data of items when changing them.

The iuse_transform action (used to transform folded stuff into the unfolded form and otherwise) only changes the item type, related item data (like item::coverage) stayed unchanged.
Vehicles don't collide flat terrain even when it's bashable.

The flat terrain check is based on the movecost being 2 (e.g. floor).
