Updated jQuery to latest version from Google Ajax API.
Integrated pull-request from BlindHunter to add the ability to override templates on a per-model basis.
Updated README.
Updated status to stable/production.
Added AttributeError exception handling for models that specify a SortableForeignKey that does not inherit from Sortable.
Added template support for nested objects that are sortable by a foreign key, where the foreign key is not sortable.
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.
