  - Removed deprecated `removeReaderByName`, `addDeclarations` and `removeDeclarationByName` methods on `Options`.
  - Removed `ProjectReflection.directory`, it was unused by TypeDoc and not properly tested.
  - Removed `ProjectReflection.files`, this was an internal cache that should not have been exposed, and shouldn't have existed in the first place, since removing it made TypeDoc faster.
  +- Removed `ReflectionGroup.kind` since groups can now be created with the `@group` tag.
  - Removed `ReflectionKind.Event`, the `@event` tag is now an alias for `@group Events`. Note: This changes the value of `ReflectionKind.Reference` from `16777216` to `8388608`.
  - Themes are now set on the document element rather than on body, #1706.
