Add a label prop for Switch

[Vehmloewff]

If the label prop is specified, then Switch would become a block element that gets no shorter than 48px, and just as tall as the label forces it to.

There could also be a left prop of type boolean (default should be false) that puts the switch on the left side of the element.

Example:

Without left:

<Switch on={true} label="Allow notfications"/>

With left:

<Switch on={true} label="Allow notfications" left={true}/>
