title: Scheduled task to open URL
body: <p>At a certain time each day, I'd like my browser to pop open a tab to a certain URL.</p>
  
  <p>My goals:</p>
  
  <ol>
  <li>be able to set the URL from the scheduled task</li>
  <li>use the default browser (rather than hard-coding it)</li>
  </ol>
  
  <p>I can't seem to accomplish both of these goals at once.  I'll post my partial solutions as answers, but I'm hoping someone will have something better.</p>
