Objects: mods name their Quick Drop objects and group them into families with reskate-objects.json

A mod's objects each got a tile of their own, titled with the raw key, so sizes or colours of one
object could not share a tile and X / Square had nothing to pick from. A reskate-objects.json in the
mod folder now gives them titles, families and categories, read at startup into a mod_objects map
kept apart from the game's own items. It only adds: taken ids and the game's items are left out.
