Allow options to be array of objects without causing warning

[kushanson]

I found that I can pass options an array of objects and then custom render my items as needed. I was passing simple option object with URI for image and label. Would be good to update options to allow PropTypes of object or string. For now, I can just ignore the warning.

This serves very nicely as a drop down list control.

Happy new year and thanks for your feedback. I'll fix this.
