Breadcrump navigation widget - A qooxdoo contribution

The breadcrumb widget show a path split into single breadcrumb navigation items.

Example:

var breadcrumb = new go.ui.indicator.BreadCrumb()

var model = []
model.push(new go.data.PathItem('Qooxdoo', qx.util.ResourceManager.getInstance().toUri('go/ui/indicator/test.png')))
model.push(new go.data.PathItem('Widgetbrowser'))
model.push(new go.data.PathItem('Breadcrumbs'))
breadcrumb.setPath(model)

This example creates a breadcrumb path for /Qooxdoo/Widgetbrowser/Breadcrumbs.
