General improvements

[JaneIRL]

Some improvements can be made to this script:

• Saves oldStatus to a file (maybe called state.json or whatever) and loads it on startup, so that it won't re-post a status update after a restart unless the status actually changed.
• Add a timestamp or a counter or whatever, so that the script will only post an update after the new status has been detected for 120 seconds / 2 retries or whatever configurable amount of seconds/retries. This way the updates won't be too annoying when the website gets a quite restart.
