Title: added basic http redirects for #54

Added a simple factory for creating url redirects.
It can be used with Finagle Paths or raw strings.
You can also optionally set the string content and the Respond type.

Some examples:
```scala
object SomewhereService extends Service[HttpRequest, HttpResponse] {
def apply(req: HttpRequest) = Redirect(Root / "somewhere").toFuture
}
```
```scala
object GoogleService extends Service[HttpRequest, HttpResponse] {
def apply(req: HttpRequest) = Redirect("http:www.google.com").toFuture
}
```
