Script Summary: Automatically confirms the 90-minute periodic prompt asking "Are you still there?", so you can talk on Google+ Hangouts without worrying about being disconnected.
1.0 - Initial release.
1.0.1 - Changed method of finding "Yes" button; old method was unreliable since the id attribute was not constant. Now uses jQuery. Removed check for toolbar.
1.0.2 - Added delayed start. Added @updateURL in UserScript header for Greasemonkey auto-updater.
1.0.3 - Fixed delayed start not working.
1.0.4 - Changed interval to 15 seconds. Added 'click' mouse event to click() method; hopefully this fixes the problem.
1.0.5 - Removed the 'click' event; not needed. Confirmed working on Google Chrome.
1.0.6 - Modified click method to work in Firefox.
1.0.7 - Moved simulate() and simulateClick() into the checkForPrompt() method so they will be properly called when the script is loaded.
1.0.8 - Updated jQuery version to 1.9.0.
A simple script that checks if the "Yes" button exists that comes up every 90 minutes confirming that you are still in the hangout. If it exists, the script sinulates a click on the button. The script runs on https://plus.google.com/hangouts/_/* (that's where Google+ Hangouts take place) and loops every 15 seconds. Very useful if you want to use Hangouts without constantly paying attention the the Hangouts window.
