The `:attributes` adapter is the default one, but it did not support key transformation. This was very surprising behavior, since the "Configuration Options" page in the guides didn't mention that this behavior was not supported by the attributes adapter. This commit adds key transform support to the attributes adapter, and adds documentation about the default transform for the attributes adapter (which is `:unaltered`). This commit also handles arrays when transforming keys, which was needed in the case where you're serializing a collection with the Attributes adapter. With the JSON adapter, it was always guaranteed to pass a hash to the KeyTransform functions because of the top-level key. Since there is no top-level key for the Attributes adapter, the return value could be an array.
