Reformat changelog for upcoming changes.

Rearranges and reformats the changelog entry for the upcoming version to
better fit with the Keep a Changelog guidelines. We're already grouping
stuff decently, but we can do better with section headers. In an entry
like this one with lots of changes, it just makes the reading experience
much better, and we do want people to read the changelog :)

 ## [Unreleased]
+### Added
 - A new `ready` state is now available for arena sign templates. Signs are in this state when all players in the lobby have readied up, but the arena has not yet started due to a start delay timer. Check the wiki for details.
 - Arena signs now support dynamic list entry variables for 4 different player lists. As an example, `<notready-1>` results in the name of a player in the lobby who hasn't readied up yet. This is useful for visualizing who is holding up the lobby. Check the wiki for details.
 - Elytra are now supported chest pieces in class chests.
-- Elytra and Netherite armor pieces now correctly auto-equip if specified in the generic `armor` node in classes in the config-file.
 - Boss names now support color codes.
 - New per-arena setting `arena-warp-offset` can be used to spread out players randomly by an offset from the arena warp. This should help prevent players taking suffocation damage.
 - New per-arena setting `announcer-type` determines where to display per-arena announcements such as wave spawns, auto start timers, boss abilities, and death messages. Options are `title` (default) or `chat`.
@@ -22,22 +22,29 @@ These changes will (most likely) be included in the next version.
 - The new `nothing` keyword can be used to _not_ grant a reward. This can be used in a crude way to create "loot table"-style reward systems where there is a _chance_ that something is reward, but it might also just be nothing.
 - Boss rewards also support the `all()` and `random()` functions as well as the `nothing` keyword.
 - New command `/ma addreward <player> <thing>` can be used to add a reward to an arena player's reward list. This can be useful for hooking into the rewards system from scripts or other plugins.
+- The `/ma addarena` and `/ma autogenerate` commands now supports multi-word arena names.
+
+### Changed
 - The Root Target ability now uses potion effects (slowness, slow falling, and negative jump boost) instead of repeated teleports. This should make for a smoother root experience.
 - 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 arena and/or 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.
-- The `/ma addarena` and `/ma autogenerate` commands now supports multi-word arena names.
 - Leaderboards now use arena and class 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.
+- Config-file errors imposed by incorrect usage of `/ma setting` no longer cause "internal errors". Instead, the errors are properly communicated in the command output similar to how the `/ma reload` command works.
+- Guardians and elder guardians no longer instantly retarget players when they break line of sight. This should make their behavior work a bit closer to vanilla.
+- (API) MobArenaHandler now returns class name slugs in the `getPlayerClass()` methods.
+
+### Fixed
+- Elytra and Netherite armor pieces now correctly auto-equip if specified in the generic `armor` node in classes in the config-file.
 - 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.
 - The `player-time-in-arena` setting has been fixed.
 - The `soft-restore` setting has been fixed for blocks broken by players. Note that the functionality is still unreliable for non-trivial blocks.
-- Config-file errors imposed by incorrect usage of `/ma setting` no longer cause "internal errors". Instead, the errors are properly communicated in the command output similar to how the `/ma reload` command works.
-- Guardians and elder guardians no longer instantly retarget players when they break line of sight. This should make their behavior work a bit closer to vanilla.
 - Items in class chests are now cloned before they are made unbreakable and given to players. This fixes an issue where setting `unbreakable-weapons: false` had no effect on the items. Note that any affected items in existing class chests will need to be replaced.
+
+### Removed
 - The MagicSpells integration has been removed. This means that the extra `magicspells.yml` config-file (if it exists) no longer does anything and can be removed.
-- (API) MobArenaHandler now returns class name slugs in the `getPlayerClass()` methods.
 
 ## [0.104.2] - 2020-01-03
 - The region overlap check now works across both arena and lobby regions, i.e. all four combinations of intersections between two regions (arena-arena, arena-lobby, lobby-arena, and lobby-lobby) are evaluated.
