Button's support for this.props.children?

[geekingfrog]

I'd like to be able to customize some button content with complex elements, where a label is not enough.
The component icon button is also not suitable since it's rounded.
What I'd like would be something like:

<FlatButton>
  <Icon icon='action-alarm-on'/> wake up!
</FlatButton>

This can be done easily by replacing this line with

<span className="mui-flat-button-label">{label || this.props.children}</span>

and making the property label optional.

What do you guys think?

Any ETA for this? I'll be glad to help and add a pull request if you need it.

I think we should make an icon prop instead of using this.props.children?

This would be in line with how IconButton is set up:
