Simplify the management of redirects, non mappable articles and categories

Store redirects and non mappable items in three lists:
data/wikipedia/non_mappable/redirects
data/wikipedia/non_mappable/articles
data/wikipedia/non_mappable/subcategories

instead of one big configuration file.
Add new categories and update old ones

Trafori stradali in Italia‎
Malghe
Conventi d'Italia

Config file on fmach server should be overwritten with the one on git

(It would be better to save categories dates on another file).
