Want to set Jetty to hot deploy, but there is no deployer

Question

I'm running a SmartFox 1.6 server with included Jetty servlet container. I want to configure Jetty to automatically deploy new web apps. Normally this is as simple as adding a scanInterval to the deployer:

<Call name="addLifeCycle">
  <Arg>
    <New class="org.mortbay.jetty.deployer.ContextDeployer">
      <Set name="contexts"><Ref id="Contexts"/></Set>
      <Set name="configurationDir"><SystemProperty name="jetty.home" default="."/>/contexts</Set>
      <Set name="scanInterval">1</Set>
    </New>
  </Arg>
</Call>

However, I can't find a deployer at all in the Jetty config file, pasted below. The config is the default config included with Smartfox.

Sorry for needing to include the entire config file, but I wouldn't know which blocks are relevant. Where can I set the scanInterval in the settings below?
