* Documentation:
*  Once enabled, the page will show up at the URL "home", so if you want
*  this to be the front page of your site, you should go to "Board Config"
*  and set "Front Page" to "home".
*  <p>The images used for the numbers can be changed from the board config
*  page. If you want to use your own numbers, upload them into a new folder
*  in <code>/ext/home/counters</code>, and they'll become available
*  alongside the default choices.
