Support a way to "Provide default control icons"

[Y-Moshe]

Hi,
while using this library I came across using the <Controls /> component but I didn't like the icons, so I think this little change makes that component friendly and customizable

I have made the necessary code changes that are required for this,
Also, I have found that this "discussion" has already been posted, so maybe it is worth implementing as it proves that I'm not the only one :)
