Fix minor spelling error on one of the Program Options

[bob3d]

Please. fix the minor spelling error for the Program Option "Disable Task Tray Baloon Notification".  "Balloon" has two ells.  It's a very minor fix... should take almost 45 seconds to correct. 

Thanks for all the good work you've put into this useful tool!

Respectfully,
