Prop "title" is ignored

If I pass the `title` as a prop to the `Checkbox` component, it will be removed before passing it to the HTML attribute `title`.
Like the `data-*`, `aria-*` and `role` attributes it should be passed over to the HTML.

E.g.
`<Checkbox title="Dr. Prof." />`
should be mapped to
`<input type="checkbox" title="Dr. Prof." />`.
