• Fixed: better support of react-router routes that don't have slashes
  (#941 - @MoOx)

• Added: better support of react-router routes (IndexRoute and trailing slashes)
  (#941 - @MoOx)

• Removed: declaration-block-no-ignored-properties has been removed from
  our stylelint preset because this rule is not reliable (and deprecated).
  This is not a breaking change.
