Add HTML typings to all components, and make sure ...props are passed down to the correct element

[julrich]

Like here: 8b55c94

The ...props should be added as an argument, as well as spread into the correct tag of the component. The type to add depends on the tag the ...props end up on (e.g. <div {...props}>..</div> -> HTMLDivElement, <button {...props}/> -> HTMLButtonElement)
