Support for stacked progress bars

[Hekku2]

It would be nice to have support for stacked progress bars

Suggestion for API
data-bind="progress: { stacked: arrayOfProgressBinding }"
And arrayOfProgressBinding would be something like

arrayOfProgressBinding = [
{value: valueSuccess, type: typeSuccess, text: text, textHidden: hidden, animated: animated, striped: striped},
{value: valueWarning, type: typeWarning, text: text, textHidden: hidden, animated: animated, striped: striped},
{value: valueError, type: typeError, text: text, textHidden: hidden, animated: animated, striped: striped}
];
