title: `ionic start` CLI arguments ignored
body: <p>Maybe I'm missing something, but no matter what I try/do, the arguments I provide to <code>ionic start</code> in the CLI are not copied to <code>config.xml</code> and as a result, I need to manually edit these before running <code>ionic build</code> or my project properties are built with the incorrect app name/ID etc.</p>
  
  <p>If I run:</p>
  
  <pre><code>ionic start -v -a MyApp -i com.me.myapp IonicApp blank &amp;&amp; ionic build
  </code></pre>
  
  <p>Then neither <code>MyApp</code> nor <code>com.me.myapp</code> are set as my app name/ID respectively.</p>
  
  <p>Am I missing something obvious?</p>
  
  <p>I am using ionic@2.0.0 beta #19, but it occurs on ionic@1.7.14 (latest stable). I am using node@4.3.2 (latest LTS version).</p>
