------------------
- Deprecated aliases were replaced on tests.

- Keep the acquisition context of the blob in index_html, as otherwise
we cannot get the http__etag method.

- Move download implementation (the ``index_html`` method) to the blob
wrapper class. The wrapper object is now directly viewable via the
Zope 2 publisher.
This change adds support for publishing of the original image data
for any image field via the scaling view (even for fields that have
been added via schema extension).
Previously, if the blob wrapper was published for a content object
that did not derive from the provided image class, Plone's default
``index_html`` template would be used, rendering an HTML page
instead of the image.
