> Remove AkkaUtils.ask to encourage explicit future handling

> {{AkkaUtils.ask}} asks another actor and awaits its response. Since this 
> constitutes a blocking call, it might be potentially harmful when used in an 
> actor thread. In order to encourage developers to program asynchronously I 
> propose to remove this helper function. That forces the developer to handle 
> futures explicitly.
