Add an option to call to middleware by using req object

[Aminadav]

See this code for example:

app.get('/middleware1',function(req,res){
           /*
                  use req object instead of app object
          */
           req.runMiddleware('middleware2',{},function (){})
})

Fixed in the new version. But you need to call it from the res object.
