Description Brent Fulgham 2018-05-09 14:01:19 PDT 
To protect WebKit from malicious software, we should restrict the classes we will unarchive when passed a bundle parameter. Currently we allow anything descending from NSObject, which is far to large a set of objects.

This is follow-up work to Bug 178484.
