~~~~~~~~~~~~~~~~~~~
- Rename management command to ``process_imagefields``, and add
``--all`` option to process all imagefields.
- Fixed a bug where not all image fields from base classes were picked
up for processing by ``process_imagefields``.
- Added the ``IMAGEFIELD_AUTOGENERATE`` setting, which can be set to a
list of image fields (in ``app.model.field`` notation, lowercased) to
only activate automatic processing of images upon model creation and
update for a few specific fields, or to ``False`` to disable this
functionality for all fields.
- Added system checks which warn when ``width_field`` and
``height_field`` are not used.
- Changed ``process_imagefields`` to process image fields in
alphabetic order. Also, made cosmetic changes to the progress output.
- Added a test which verifies that generating processed image URLs is
not slowed down by potentially slow storages (e.g. cloud storage)
- Fixed the PPOI JavaScript to not crash when some imagefields have no
corresponding PPOI input.
