Title: Complaints of errors in Xcode 4.3 with the NSCachedURLResponse category

When using Xcode 4.3, a warning message is raised because of the overridden methods in the category on NSCachedURLResponse.

We've written a simple wrapper instead which conforms to the NSCoding and NSCopying protocols and does not use categories. From our limited testing the approach seems to work and alleviates the error.
