[Switch] autoFocus

[Mangatt]

There is problem with Switch component autoFocus (Material UI 1.4.0):

<Switch
	inputProps={{
		autoFocus: true
	}}
/>

Although input is correctly focused in browser (and switching with space key works), component focus is not highlighted.

For autoFocusing element, there should probably be autoFocus property on Switch component:

<Switch autoFocus />

And I guess that focused styling on unchecked element should be changed - white glow in light theme is practically invisible.

<Switch required />

Should probably pass required attribute to input element as well.

@Mangatt I agree, I think that we should be using the same tradeoff between Switch, Radio, Checkbox and the Input. The properties that we should forward but we miss in the SwitchBase component:

• autoFocus
• readOnly
• required
