- Shorten very long class names (motivated by TODO in AbstractDecoratedStyledTextCellDatabindingEditingSupport)
  - TextCellEditorWithTextStyledTextActionHandler -> StyledTextCellEditor
  - AbstractDecoratedTextCellWithTextStyledTextActionHandlerDatabindingEditingSupport -> AbstractDecoratedStyledTextCellDatabindingEditingSupport
  - AbstractTextCellWithTextStyledTextActionHandlerDatabindingEditingSupport -> AbstractStyledTextCellDatabindingEditingSupport

- Update rating of affected classes
  - Resolve minor issues (many documentation)
  - Try to keep current rating where appropriate since the changes are pure renamings
