Use Arena "config name" on leaderboard headers.

Going forward, it should be possible to show "pretty" arena names by
simply using a pretty name in the config-file instead of slug-like names
now that slugs are on the horizon.

 - Permissions for arenas and classes are now based on "slugs". It is now possible to configure permissions for arenas and classes with multi-word names (including "My Items"). Check the Permissions page on the wiki for details.
 - Commands that resolve class names now consistently resolve and tab complete "slugs" instead of arbitrarily "squashed" names. This greatly improves support for multi-word names.
 - The class signs generated by the `/ma autogenerate` command now use class names from the config-file instead of arbitrarily "squashed" names.
+- Leaderboards now use arena names from the config-file instead of arbitrarily "prettified" names.
 - Using `spectate-on-death: true` no longer forces players out to their join location/exit warp before moving them to the spectator area. This should prevent "jumpy" behavior in multi-world setups.
 - Players should now properly respawn at the spectator area rather than at world spawn on servers with plugins that override respawn locations.
 - Config-files with missing `pet-items` nodes no longer errors. A missing `pet-items` node in `global-settings` is treated as empty, i.e. no pet items will be registered.
