Periodically browse other server URLs. an alternative to online cron services.

Remixed from https://www.val.town/x/healeycodes/isMyWebsiteDown
and I also got a hint from https://www.val.town/x/stevekrouse/status

1. Remix this Val.
2. Browse to the config.json and replace the URL you want to work with in the cron.
3. Set the CRON trigger in main.tsx. You can set the execution interval in the trigger settings.

Depending on the servers used by Val Town and how they work, there may be servers that block referrals.
