pass through `id` prop

just as className is appended to the class name of the rendered element, the passed in id attr should be used as the id for the rendered element.

This will allow <Select> components to work with the alternative label form, e.g.

<label htmlFor='my_input'>my input</label>
<Select id='my_input' {...props} />

in version >= 2 to set the id on the Select use <Select inputId="foo" />.

I just noticed there’s an inputProps prop which allows you to set the id on the input itself. Can you try that out?
