Nancy.Testing.Brower.HandleRequest shall be public

When Nancy.Testing.Brower.HandleRequest would be public, this would allow dynamic testcases based on path and http-method. A Nunit definition would then look like this:

    [TestCase("GET", "/users")] 
    [TestCase("POST", "/users")]
    [TestCase("DELETE", "/users/3")]
