Assign the `id` and pass the `event` into the Picker's `onChange` 
Hello,
I am using `SketchPicker` inside a component that is used several times and that in the various uses I differentiate through `id`.

The problem is that I can't assign the `id` and pass the `event` in the Picker's `onChange`... what can I do?

Furthermore, is it possible not to have inline css but to have it in a dedicated style sheet?

Thankss
