If the remote ladder's update rating method dosen't receive
a response from the login server, it will not change the user's
mmrCache for the format, resulting in future ladder matches using
an outdated ELO until the server receives a response at the end of
a future match.
This is the cause of issues such as users with 1400 ELO being matched
with users with 1000 ELO with a 10 second wait time in current gen OU.
Ensuring the rating is up to date was discussed, but for cases such as
a user searching for a new match before a response is received (or an
error occurs) we decided to accept the mmrCache being at most 1 game
behind, which this change.
`item.itemUser` replaces `item.zMoveUser`, and is a new field
representing a list of possible users of an item, for items that are
restricted to specific species.
`item.zMoveUser` is a base forme for items that affect every forme, and
a forme name otherwise (forme name is currently only used for
`forcedForme` uses).
Arceus is a weird case. Both generic Z crystals and Plates, while
having unique effects on Arceus, also have effects on other Pokémon.
For this reason, Arceus isn't listed as an `itemUser` of either of
these item types - use-cases that want this should also check
`item.forcedForme`.
This is mostly intended to be useful to move-searching and custom
rules (like NatDex, which will only allow past-gen items associated
with removed species).
Right now the /mnm command results in warnings that the mega stone is a CAP stone, even when it is not. This is because isNonstandard is now set to "Past" instead of undefined.
`server/chat-commands.js` is now a directory. It's been split into
`core`, `moderation`, and `admin`. `info` and `roomsettings` from
`chat-plugins` have also moved to `chat-commands`.
Some cleanup:
- Bot commands for inserting HTML into rooms like `/adduhtml` have been
moved from `info` into `admin`.
- `/a` has been renamed `/addline`, for clarity (and also moved from
`info` into `admin`).
- Room management commands like `/createroom` and `/roomintro` were
moved to `room-settings`
- `chat-commands/admin` has been TypeScripted
