Refactored how the sortable_by properties get populated by looping over the model fields until we get to the SortableForeignKey, then grabbing properties from the field and its related data.
Refactored ORM calls to properly order objects by the sortable_by property to ensure objects are grouped correctly in the sortable change list template after being passed through dynamic_regroup.
Fixed missing import for jquery.effects.core, again.
Refactored sortable_by classmethod into a property.
Added backwards compatibility for pre 1.1.1 versions that still have sortable_by defined as a classmethod.
Need to address dynamic regroup template tag to see why categories are not being grouped properly in sample app.
Added highlighting to sorted inline.
Added migrations to add Note class to database.
Added SortableInlineBase for checking type of model specified in inline model subclasses Sortable.
