Add style prop to the Form component

[Martinnord]

What

Add a style prop to the Form component.

Why

Since almost every elements has a style prop it would be awesome to see one here as well. It will open up more possibilities when styling your form and maybe speed up UI prototyping.

How

TBA ;-)

Thanks for pointing this out, @Martinnord.

I would extend the proposal of this issue to ensure props propagation to the <form> component. This could be handled by spreading the custom props before attaching the RAF-specific ones.

I will try to cover this and publish under the next patch release.

After a short look it became evident why this wasn't implemented as spreading at the very beginning. If we spread all the props from Form onto <form> component, we would propagate our custom props to a common DOM element (props like initialValues, onReset, etc.). This results into error of unknown props, and thus isn't a safe option.

I have added the support for style prop on the Form component.

However, I have stumbled upon the current CI pipeline not working properly, producing falsy negative results. There will be no new release until #287 is fixed. Thank you for understanding.
