V1.8.0: the fallen are hidden, and allies can revive the dead

- A dead character, or a monster or NPC at 0 HP, is out of the fight: the
  server no longer sends it to players, target marks included, and it has
  no turn. Healing or reviving brings it straight back.
- The DM's screen leaves the fallen out too until "Show dead" is ticked,
  which lists them in a group of their own, marked hidden.
- Players see dead characters by name in a Fallen box. The player whose
  character is on turn in a battle gets "Try revive" there if that
  character is on their feet and knows a spell that revives, at a level
  they can cast. The dead come back at 1 HP.
- Spells have a "Revives" tick in the campaign's spell list. Revivify and
  Raise Dead have it, in the library and in existing campaigns.
- A dead character cannot be added to an encounter until revived.
- All packages at version 1.8.0.

+- An **ally** tries it: in a battle in progress, the player whose character is

+  ([SPELLS.md](SPELLS.md)), at a level they can cast. The library's Revivify
+  (level 3) and Raise Dead (level 5) are ticked already.
