Tool contract 11.17.0

The time a timeline item shows is the time it sorts by; evidence names the other side; a first friend stays a friend.

• elixir_timeline, clans_timeline and clans_members_timeline: at_unix and local now name sort_at, so a sitting reads at its last battle, in the order served. at is unchanged: a sitting's first battle.
• elixir_timeline evidence: each battle gains opponents, each { player_tag, name, crowns, clan_tag, clan_name } by in-game name, empty when the record holds none.
• elixir_track_player: a first player named friend or watching stays that and does not become your primary. applied.relationship says what was applied, and a note says the account has no player of its own until you name one with primary. A first player with no relationship still becomes your primary.

JSON API unchanged.
