title: Exclude all except 1 subdirectory from teamcity checkout rule
body: <p>I have a VCS root with the following checkout rules:</p>
  
  <pre><code>+:.
  -:externals
  +:externals/jQuery
  </code></pre>
  
  <p>However TeamCity doesn't seems to do a checkout for <code>externals/jQuery</code> directory.
  Is there anyway to achive this, except by creating a separate VCS root for this directory?
  I'm using TeamCity 8.0 latest EAP.</p>
  
  <p><strong>Update (2017)</strong></p>
  
  <p>Since TeamCity 10 it's seems that it's possible to do what this question was asking</p>
  
  <pre><code>+:**/* =&gt; target_directory
  -:**/folder1 =&gt; target_directory
  </code></pre>
