Title: fix for onhashchange detection for IE in compatibility mode

This might be an edge case, but I found it essential to get routing to work on my app when hosted in SharePoint 2010. The onhashchange event does not work in IE9 when document mode is set to IE8. SharePoint uses the header which force sets document mode to IE8 and breaks routing.
