title: Akka won't override application.conf with command line parameters
body: <p>I thought since akka 2.1.4 uses typesafe config, it would just override whatever -D parameter I throw at it via command line, like play framework does. Turns out it doesn't seem to work that way. Just adding a <code>-Dakka.remote.netty.port=2552</code> doesn't really change anything when added in to the commandline. Do I have to enable anything to make overrides work?</p>
  
  <p>Additional info: I tried using the -D parameters in the Intellij launcher and with <code>java -cp app.jar -Dakka.remote.netty.port=2552</code> after doing an <code>sbt assembly</code></p>
