Select element cannot be disabled

[julen]

If you pass the disabled prop to the <Select /> element, it's completely ignored.

This should:

1. Pass the prop to the hidden <input /> element.
2. Do not render the <Input /> element from react-autosize at all, and only display the placeholder instead.
3. Adjust the default styling for a disabled <Select /> element.

If you are OK with it, I can provide a PR for this.

Good call @julen, I'd be really happy for a PR for this. If you want, @jossmac can do the styling for an -is-disabled class.

So unfortunate I have this locally done but didn't find time to create the PR :( (can't assign issues myself)
