Since `DefaultHostnameVerifier` may fail to load on JVMs that don't have the sun JSSE provider, let's wrap this in something like:

Change to

```scala
try {
  asyncHttpConfig.setHostnameVerifier(
    this.getClass.getClassLoader.loadClass("play.api.libs.ws.ssl.DefaultHostnameVerifier").newInstance()
  )
} catch {
  /* note, NonFatal is innappropriate to use here because it doesn't catch all the Errors that could be thrown when loading a class */
  t =>
    Logger.warn("Unable to load default hostname verifier, hostname verification will be disabled", t)
}
```
