Bug 5184 - Upgrade jQuery to the latest version (staff client)

Upgrade jQuery in the staff client. Besides the change
to the jQuery file syntax has been changed wherever this
syntax was written:

$(foo).attr("checked","");

The new correct way to un-check a checkbox:

$(foo).removeAttr("checked");

I also removed some JavaScript altogether from
branch-transfer-limits.tt which used the old syntax but
which wasn't used on the page at all anymore.
