title: How to get / set Unity Editor main window title?
body: <p>I'm creating a tool that shows your current branch in Unity window title.</p>
  
  <p><strong>But I cannot get or set the title</strong>. So far I managed to set <a href="https://github.com/Unity-Technologies/UnityCsReference/blob/96187e5fc1a23847206bf66b6f2d0e4a1ad43301/Editor/Mono/ContainerWindow.cs#L250" rel="nofollow noreferrer"><code>title</code></a> property, I used <a href="https://github.com/Unity-Technologies/UnityCsReference/blob/96187e5fc1a23847206bf66b6f2d0e4a1ad43301/Editor/Mono/ContainerWindow.bindings.cs#L88" rel="nofollow noreferrer"><code>Internal_SetTitle</code></a> (using Reflection), but the values does not show up in the actual window title.</p>
  
  <p>On the contrary, I can set <a href="https://github.com/Unity-Technologies/UnityCsReference/blob/96187e5fc1a23847206bf66b6f2d0e4a1ad43301/Editor/Mono/ContainerWindow.bindings.cs#L37" rel="nofollow noreferrer"><code>position</code></a> property of main window just fine using the same method.</p>
  
  <p>Did anybody manage to alter the title using <code>UnityEditor</code> classes?</p>

  <p>(Probably I could work the issue around by creating native plugins for that, but I'd prefer a cross-platform / Mono solution if there is any)</p>
