Basic curing and tanning.

Hides/pelts are now perishable (and if you're desperate, edible) and
requiring curing to keep from spoiling. Cured hides can be tanned; this
process takes about two days to complete, after which they can be
activated to turn them into a single large piece of leather or fur.

Translations template update
Move the code to generate submaps to the beginning of map::loadn

Also add a debugmsg when generation failed, because that will most likely lead to a crash and there should be something (directly visible to the user, not inside a log file) that hints what the cause was.

Replace "worldx + gridx" with absx, which is calculated just a few lines above.
Move code to actualize the content of a just loaded submap into separate function
Move set_abs_sub before calling map::loadn.

map::loadn loads a single submap, it makes no sense to adjust that coordinate here, it affects the whole object.
It's far better to set this
a) when loading the map with map::load, which loads all submaps at once.
b) when shifting. It s already called there. It must be called outside of loadn there because it's not garanted that loadn(0,0, ...) is called there at all. And only when called with gridx==gridy==0, set_sub_abs is called in map::loadn.
