Added basic bulk adjustment template tag. #22
Made base class for adjustment nodes and set adjustment node to check for previously-adjusted versions.
Fixes #28, works on #22.
Moved adjustment functionality from a variety of locations (views, templatetags, AdjustmentManager) into an AdjustmentHelper class.
Moved AdjustmentHelper into utils.adjustments.
Also further centralized adjustment code onto the AdjustmentHelper.
Moved actual info_dict generation into private AdjustmentHelper methods.
Preserved iterable order in adjust_bulk template tag.
Added docs for adjust_bulk template tag.
Added BulkAdjustmentHelper and added tests. #22.
BulkAdjustmentHelper takes over the functionality of much of the BulkAdjustmentTemplateTag, which makes it easier to test. It also allows more efficient code sharing.
Implemented bulk_create usage for creating Image instances during bulk adjustment.
Added BulkAdjustmentHelper support for template-style lookups.
(Rather than just attributes.)
Updates to the admin to reflect the new AdjustedImage model.
