The Sandbox implementation provides a mechanism where apps can extend the default app sandbox with entitled extension properties in their Info.plist. WebKit does not need or use this feature, but the rules were imported when we stopped using the system sandbox. We should remove them since we don't need them, and they add to the size and complexity of the sandbox rule set.
