title: Make a newly created terminal visible (VSCode)
body: <p>I'm working on creating a new extension for VSCode using typescript. I've got almost everything working but I'd like to make the terminal I've created (using <code>vscode.window.createTerminal()</code>) visible. I've been able to send text to run commands and I thought that <code>.show</code> would work, but it did not. Is there something that I'm missing?</p>
  <pre><code>if (!hugoTerminal) {
    hugoTerminal = vscode.window.createTerminal({
      name: 'Hugo Server'
    });
  }
  
  let execCommand = 'hugo server ' + previewArguments + ' -s ' + vscode.workspace.rootPath;
  hugoTerminal.sendText( execCommand );
  
  hugoTerminal.show;
  </code></pre>
  <p>Thanks!</p>
