title: Implement "Open Containing Folder" and highlight file
body: <p>This can be a handy functionality to have in a program that works with files/folders. It's easy enough to actually open the containing folder using:</p>
  
  <pre><code>System.Diagnostics.Process.Start( *path to folder* );
  </code></pre>
  
  <p>...but how do I go about actually selecting the target file within that parent folder? If I use the Process.Start method it actually attempts to open the file.</p>
