Added hasOwnProperty filters in for..in loops
Added hasOwnProperty filters in for..in loops

I did not apply this patch back when upgrading to latest closure code. It has
an impact in our application: without the filter, cloneObject copies the
enumerable property 'remove' set by ExtJS 3.2 on Array.prototype to array
instances, and unit tests fail due to a mismatch in owned/inherited property.

I shall report this patch suggestion, as well as changes I made in goog.History
on Google Closure mailing list.
