Jchansen/add wildcard routes

1. Added wildcard route to the public site so it always redirects to the images page if the user happens to enter a bad route, or (more commonly) the user clicks a link that need to be logged in to see and the page just displays a white background because that isn't a valid route on the public site.

2. Added a DefaultRouter to the private site.  This handles the wildcard route and is intended to simply be a redirect.  Right now it redirects to the users Projects page, but can be set to Dashboard later if desired.
