Plone.app.blob

-------------------

- Revert the change to use the URL normalizer when generating content ids
based on filename and reinstate the previous (and expected) behavior.

-------------------

- Use updated version of `createScales` as monkey-patched in
`plone.app.imaging`. Refs http://dev.plone.org/plone/ticket/10186
[witsch]

-------------------

- Change test setup to reuse the same directory when setting up blob
storages, thereby fixing some BBB test issues.
[witsch]

- Remove temporary monkey wrapper for `Blob.open` used to work around an
issue with `CMFEditions`. Refs http://dev.plone.org/plone/ticket/10200
[witsch]

- Use URL normalizer when generating content ids based on filename.
[terapyon, papago, witsch]

- Update view to analyse approximate content size grouped by type.
[witsch]

- Add `z3c.autoinclude` entry point for automatic ZCML loading in Plone 3.3+.
[witsch]

- Make sure image scales from old AT image fields are removed during
migration to blob fields, when using the BlobMigrator. This closes
http://dev.plone.org/plone/ticket/10160

- Updated migration.pt to follow the recent markup conventions.

- Make it possible to delete image content.
[witsch]

-------------------

- Fix issues regarding migration from `OFS.File` and `OFS.Image` content.
[optilude, witsch]

- Revert changes to make things more robust in case of missing blob files.

[witsch]

- Try to re-fetch blobs that have been removed from a client-side ZEO cache
before giving up and raising an error. This makes it possible to control
the client blob cache size via external processes (e.g. `cron`) even with
ZODB 3.8. See http://dev.plone.org/plone/changeset/32170/ for more info.
[svincic, witsch]

- Fix issue with incorrect values for "Type" catalog index after migration.
[yomatters, witsch]

-------------------

- Add support for accessing image scales via path expressions like
`here/image_thumb` for backward-compatibility.
[witsch]

------------------

- Unify the ATBlob factories (for CMF>=2.2 and CMF<2.2) while still
preventing events from being fired for the former.
[witsch]

- Fix range support for open ranges.
[j23d, witsch]

- Make the title field non-required for ATBlobs, since it will be
generated from the filename if necessary.
[davisagli]

- If a title was entered, use it instead of the filename to generate an
id for files (matching what was already done for images).
[davisagli]

- Update the CMF 2.2 version of the ATBlob factory to match a fix I made
in Archetypes 2.0a2.
