Updates to support multiple visible views with a hash or target using + between each view.  So for example if you have a items,leftView and a items,centerView the target would be set to target="items,leftView+items,centerView" and the url="#items,leftView+items,centerView".  With this change the config option I had added for visible is no longer needed, the default visible views can be indicated in the config with the defaultView just like the target. "defaultView":"items,leftView+items,centerView",
