Extensions Docs Server: Split apps from extensions

chrome/common/extensions/docs/server2/templates/articles/api_index_apps.html

 <h1 class="page_title">chrome.* APIs</h1>
-<p class="doc-family extensions">
-Chrome provides APIs such as
-<code>chrome.bookmarks</code> and <code>chrome.tab</code>
-so that extensions can interact with the browser.
-</p>
 
 <p class="doc-family apps">
 Chrome provides many special-purpose APIs like
 <code>chrome.runtime</code> and <code>chrome.alarms</code>
 to packaged apps.
 </p>
 
 <h2 id="supported">Supported APIs</h2>
 
 <p>
 Here are the supported chrome.* APIs:
 </p>
 
 <ul>
-  {{#api_list.chrome}}
+  {{#api_list.apps.chrome}}
   <li><a href="{{name}}.html">{{name}}</a></li>
   {{/}}
 </ul>
 
 <h2 id="experimental">Experimental APIs</h2>
 
 <p>
 Chrome also has
 <a href="experimental.html">experimental APIs</a>,
 some of which will become supported APIs
 in future releases of Chrome.
 </p>
 
 <h2 id="conventions">API conventions</h2>
 
 <p>
 Unless the doc says otherwise,
 methods in the chrome.* APIs are <b>asynchronous</b>:
 they return immediately,
 without waiting for the operation to finish.
 If you need to know the outcome of an operation,
 then you pass a callback function into the method.
