Rewrote the breadcrumb calculation to be more readable. Breadcrumb now has a setMaxWidth() method to set the maximum allowed width which is used to fit the breadcrumbs. The breadcrumb width is now based on the container width, passed through setMaxWidth() by the FileList class. Now using fixed widths for the test crumbs to simulate consistent widths across browsers which rendering engines might usually yield different results.
