Mono Tools debugger should break on exception, and display the standard
"Exception was unhandled by user code" dialog with options to inspect the
exception or copy the exception to the clipboard, etc.

Currently, the debugger has different behavior in different circumstances.  In
ASP.NET applications the debugger will not stop, and the exception will pass
through to be output in the webpage. 

Test Case:
Create a new ASP.NET page.  Throw an exception in Page_Load.  For instance:

using System;

namespace WebApplication1
    public partial class _Default : System.Web.UI.Page
        protected void Page_Load(object sender, EventArgs e)
            Exception ex = new Exception("oh noes!");
            throw ex;

Start the project with "Debug on Mono".  Debugger will not break.  Error will
appear in page in browser.
