Update iOS Apps in iTunes

(*
Many thanks to those unknowing contributers that share their Applescript on the web. A few that helped with this script include:
- Most of the UI Scripting came from Yoshimasa Niwa here: https://gist.github.com/4223249
- Code for checking if an app is running came from here: http://codesnippets.joyent.com/posts/show/1124

* Added several delays that seemed to be responsible for breaking this script in iTunes 11

* Added compatibility with iTunes 10 (untested, please confirm if you can)
* Added compatibility with having the iTunes sidebar activated (thanks to mattb in the comments)
