Support styling with withStyles() hook.

[davemecha]

Currently it is possible to apply custom styles via styling attributes: style, imageStyle, etc.

It would be much greater, to be able to apply styles with materialUI's withStyles() hook.

const CustomImage = withStyles(theme => ({
  root: {
    backgroundColor: theme.palette.primary.main,
  },
  image: {
    height: 'auto',
  }
}))(Image);
