Update process may spam

When updating itself sometimes there will be a couple of popup messages and it seems like the program is fetching the data and commit hashes a couple of times.

Edit : The source of this problem is the waitForJqeury function. For some reason it doesn't stop checking if jquery is loaded after it called the callback method.

Fixed in commit 8426162.
Fixed it by calling clearTimeout() before calling the callback method of waitForJquery.
I think that this interfere with any timeouts created before this method so we should take this into considiration.

Never mind, the problem is that even after jquery is loaded and the callback method is called, waitForJquery still checks if jquery is loaded and calls the callback method again.
