Changes re: client no longer running arbitrary server CSS/JavaScript

As of Zarel/Pokemon-Showdown-Client@5950a2dbbd, the client will no
longer run arbitrary JavaScript or `style` tags received from the
server. This commit makes various changes in response to this:

- Various chat commands now send `class` attributes rather than
  `style` attributes.

- The /redirect command is removed.

- The /banredirect command is removed.
Fix for the register account link
Always show the register message in the battle room
Fix typo
Use pipe protocol for register-account instead
Only send register-account to user who won (!)
Rename `register-account` message to `askreg`
Rename `challenge-string` message to `challstr`
Use `raw` rather than `chatmsg-raw`
Add admin commands to help

The help lacks information about current administrator
commands that may come in handy to know to new admins
who set up their own server.
