title: Issue with defining multiple time servers for code signing in Install4j 7.0.8
body: <p>According to the <a href="https://www.ej-technologies.com/resources/install4j/help/doc/concepts/codeSigning.html" rel="nofollow noreferrer">online documentation</a> there is a compiler variable (sys.ext.timestampUrl=&lt;URL&gt;) that can be used to define a different time server for code signing than the default, and that this variable can contain multiple URLs separated by semicolons. While I can get this variable to function correctly when passing in a single URL, I cannot get the multiple URLs to function.</p>
  <p>I've tried defining the value via <strong>General Settings</strong> &gt; <strong>Compiler Variables</strong>, as well as attempting to override this value in <strong>Media</strong> &gt; <strong>Customize project defaults</strong> &gt; <strong>Compiler variables</strong>, without success.</p>
  <p>Is there something intrinsic to the multiple URLs variable that I'm missing? We are currently on version 7.0.8 (build 7248).</p>
  <p>Thanks in advance!</p>
