Subject: [PATCH] default.js: add parseUrl

Users were seeing outdated content due to browser caching. To resolve
this issue, a unique random value is now added to the end of each URL
every time the page is loaded, forcing the browser to retrieve the
latest version of the page from the server.  By implementing this
solution, users will be able to see the most recent content without any
delay caused by outdated cache files.
