// @description This will show your estimated auto logout time and display a warning when the time drops below 30 minutes.
// @description Click on the "HITs available now" area on the top to show time remaining until logout.  Format is in a "hours:minutes" countdown.
// @description The top border changes green when time is below 30 minutes, yellow for 15 minutes and red for 5 minutes.
// @description Timing is based off Amazon's word that logouts are every 12 hours. Results may vary.
