Introduced bypass for legacy *.axd files

By registering a route, we were introducing a conflict with the legacy `*.axd` virtual resources used by **ASP.NET Web Forms** to deliver e.g. form validation scripts and AJAX "Web Method" handlers. Technically, we don't need any routes registered here, since the **OnTopic Editor** doesn't use them itself, and the host site isn't actually hosting a real **OnTopic** implementation. That said, I'm keeping in the `Ignore()` rule since it's an easy detail to overlook; this way, anyone having issues setting this up will have some guidance.
