Dialog: Extend buttons option docs to cover icons or other button widget options #208
Description
Currently the docs don't tell how to use icons with the buttons option. The relevant part of the implementation in dialog:
buttonOptions = {
icons: props.icons,
text: props.showText
};
delete props.icons;
delete props.showText;
$( "<button></button>", props )
.button( buttonOptions )
.appendTo( that.uiButtonSet );In addition, the default for the buttons option is wrong, its an empty array.
