title: Can't branch from the TortoiseSVN repo browser
body: <p>I need to branch from a tag and I would ideally like to do it through the repository browser. The problem is that there is is no <code>Branch/tag</code> option in the context menu of the repo browser.</p>
  
  <p>The reason for this is that, if I do it via Windows Explorer, I need to <code>svn update</code> the tags folder, which can take quite a while. This can be mitigated by doing an <code>svn checkout</code> of the particular tag, but this can still take some time, and is (slightly) more work that just doing it through the repo browser.  </p>
  
  <p>Does anyone know why this command is not available in the repo browser? I think that the <code>Copy to...</code> option might essentially do the same thing.</p>
