* Don't bother archiving / unarchiving data. This change upgrades to PINCache 3.0.1-beta which supports custom archiving and unarchiving. This allows us to avoid using NSArchiver/Archiver which adds a small amount of disk space overhead and between .5 and 10 ms (on an iPhone 4) for each encode / decode. To support this, we *do* have to add versioning for the cache and destroy it for the old versions. I considered adding a process to migrate the images, but because that would have to occur on startup and process all existing images, it could cause issues for very large image cache databases, so I decided against that. * Fix warnings * Fix invalid object test * Cleanup, thanks @chrisdanford!
