Moved client filters into a trait
Merge branch '2.3.x_2.10' of github.com:scalatra/scalatra into 2.3.x_2.10

Fixed problem where serialized data was getting wrapped inside of content element
Updates log message to properly include a named ClientFilter
Core only requires scala.concurrent, not Akka. 2.10 only.
