datepicker reuses a variable declared in an enclosing function as a catch block variable. Some browsers (specifically IE8) does not create a new scope for the catch block and as a result linters like JSLint and Caja complain about this reuse. In this case, the variable name is not a good name for the exception either.
This change renames the "event" catch variable to "err" to avoid the problem.
