Add boss abilities with `all` modifiers.

Introduces four "new" boss abilities that work like their pre-existing counterparts, but affect all players in the arena. This makes the four _ability sets_ a bit more complete, as it were, in that it is now possible to choose between single targets, nearby, distant, or _all_ players for the given abilities.

Closes #434

 - New monster variant `angry-bees` can be used to spawn angry bees.
 - Pet names are now per-class configurable via the optional `pet-name` property, which defaults to `<display-name>'s pet` (the `<player-name>` variable is also supported).
 - New per-arena setting `auto-leave-on-end` can be used to automatically "kick" spectators when the current session ends.
+- Added boss abilities `disorient-all`, `fetch-all`, `pull-all`, and `throw-all`. These abilities work like their target-specific and distance-based counterparts, but affect all players in the arena.
 - (API) MobArena's internal command handler now supports registering pre-instantiated subcommand instances. This should make it easier for extensions to avoid the Singleton anti-pattern for command dependencies.
 - (API) MobArena now fires MobArenaPreReloadEvent and MobArenaReloadEvent before and after, respectively, reloading its config-file. This should allow extensions and other plugins to better respond to configuration changes.
