Add "No Survivor Armor" mod

When this mod is enabled for a world, this blacklists survivor armor
i.e. they're removed from item spawns and cannot be crafted.

This adds some variety to late-game min-maxing of armor protection and
storage by eliminating the most obvious choices.
Removed FONTDATA from paths. data/fontdata.json now is legacy and config/fonts.json is actual fonts file
Use legacy and user fontdata in WinCurse
strcpy -> strncpy
Drastically cuts the amount of mutagen

Never did occur to me to simply make it its own spawngroup.  This cuts
free mutagen in labs by, oh, about 75% (one in three to even be allowed
to roll for it, and then it's kinda paltry).

Recipes are still around.  Have fun.
