Extracted local storage adapters' into a base class
refs https://github.com/TryGhost/Toolbox/issues/95 - The MediaStorage adapter and LocalFileStorage were almost identical, having a common base class makes sense here. - Having a distinct class for the "LocalFileStorage" makes it easy to spot the implementation difference from the StorageBase - the "saveRaw" method, which is not present in the StorageBase - The LocalFileStorage will become an LocalImageStorage in next commit as that name corresponds way better to what it does! - Test files need a good cleanup
