title: use specific lein-cljsbuild config in repl-launch?
body: <p>Is there a way to specify only build a specific build configuration via repl-launch?</p>
  
  <p>Maybe something like:</p>
  
  <pre><code>lein trampoline cljsbuild &lt;build_config_id&gt; repl-launch chrome
  </code></pre>
  
  <p>I'd like my :dev and :prod build configurations to output to the same file so that I don't have to worry about having an index-dev.html which includes cljsoutput-dev.js etc.</p>
  
  <p>Currently I start my server with</p>
  
  <pre><code>lein ring server-headless 3000
  </code></pre>
