title: Misspelled Ace Editor Options
body: <p>I have implemented an Ace editor setup for PHP (which is working fine), but when I try to set additional options using Ace's API, I receive warnings in the console.</p>
  
  <p>Here is the code used to init the editor and try to set the options;</p>
  
  <pre><code>ace.require("ace/ext/language_tools");
  ace.require("ace/ext/emmet");
  
  // PHP
  var phpeditor = ace.edit("php_inc");
  phpeditor.setTheme("ace/theme/dreamweaver");
  phpeditor.getSession().setMode("ace/mode/php");
  phpeditor.setOptions({
          enableSnippets: true,
          enableLiveAutoComplete: true,
          enableBasicAutocompletion: true,
          showPrintMargin: settings.showPrintMargin,
          useSoftTabs: false,
          fontSize: settings.fontSize,
          showInvisibles: settings.showInvisibles,
          behavioursEnabled: settings.behavioursEnabled,
          tabSize: settings.tabSize,
          useWrapMode: settings.useWrapMode,
          useWorker: settings.useWorker,
          setHighlightActiveLine: false,
          enableEmmet: true
      });
  </code></pre>
  
  <p>And here are the console warnings I get;</p>
  
  <pre><code>misspelled option "enableSnippets" ace.js?ver=3.9.1:5207
  misspelled option "enableLiveAutoComplete" ace.js?ver=3.9.1:5207
  misspelled option "enableBasicAutocompletion" ace.js?ver=3.9.1:5207
  misspelled option "setHighlightActiveLine" ace.js?ver=3.9.1:5207
  misspelled option "enableEmmet" ace.js?ver=3.9.1:5207
  </code></pre>
  
  <p>Any help will be greatly appreciated.</p>
