Add summon item tooltips and make the Altar of Summoning unbreakable

The four Altar of Summoning items didn't say what they do. Add two
tooltip lines to each one: the Meet Your Fight boss it summons (using
the boss entity name, so it follows the game language) and where to
use it (the Altar of Summoning in the Coliseum). en_us and es_es.

  hauntedbell -> Bellringer
  devilsante  -> Dame Fortuna
  duskkey     -> Rosalyne, Blade of Dusk
  fossilbait  -> Swampjaw

The altar has a hardness of 1, so players could mine it out of the
Coliseum. It is now unbreakable outside creative mode: no break
progress when mining, server-side break cancelled, ignored by
explosions and by block-breaking mobs (Wither, Ender Dragon...).

    Add inventory hint tooltip to the Totem of Undying

    Inventory Totem lets the Totem of Undying trigger from any inventory
    slot, but players don't know that and keep holding it in their hand.
    Add a gray italic tooltip line under the item name saying it works from
    anywhere in the inventory, with en_us and es_es translations.

    Only the vanilla totem is affected (the only one Inventory Totem
    checks), and the line is shown only when Inventory Totem is loaded.
