Revert "upgraded jquery to 1.10.2"
The upgrade broke functionality. Will change "prop" to "attr" instead.

This reverts commit 0fc5aca052dc317e05309ad5cfcebfb906e5f2b4.
Changed prop to attr for compatibility with jquery 1.3 (see http://jquery-howto.blogspot.com/2008/12/how-to-check-if-checkbox-is-checked.html)
