Revert "Merge branch 'WarningResolutions' of git://github.com/AkrionXxarr/Cataclysm-DDA"

This reverts commit b8b08ba99a20c820230fb77918e8334a92b0dd89, reversing
changes made to d5152fdc3dc34eff1730ca39a7cfc63be53082b8.

Justification: Apparently, Whales used represented certain states using negative values in the inventory
system, and perhaps in other instances. This branch replaced a bunch of
ints with unsigned ints, for no real reason.

I think that this also causes the initial NPC's needs vector to become
corrupted.

Conflicts:
	bionics.cpp
	game.cpp
	graffiti.cpp
	map.cpp
	overmap.cpp
	rng.cpp
