zio fork 1.8.2b-zio16: backport unban, rename and css_history from upstream 1.9.0

From upstream 530f603:
- css_unban updates the ban cache at once (and clears the engine banid with
  UnlockedCommands) instead of waiting up to a minute for the cache refresh.
- css_prename is saved in sa_renames (migration 017) and re-applied on connect and
  name change, so it survives restarts. css_rename from a hidden admin renames again.
- New css_history command and Players > History menu entry. Commands missing from an
  existing Commands.json are registered under their default name.
- Migrations are copied with a glob, so 017 reaches the build output.

Upstream's admin-loading changes, css_say change and css_penalties fix are left out.
