* Allow part category table to be ordered by part count * Add queryset annotation for part-category part-count - Uses subquery to annotate the part-count for sub-categories - Huge reduction in number of queries * Update 'pathstring' property of PartCategory and StockLocation - No longer a dynamically calculated value - Constructed when the model is saved, and then written to the database - Limited to 250 characters * Data migration to re-construct pathstring for PartCategory objects * Fix for tree model save() method * Add unit tests for pathstring construction * Data migration for StockLocation pathstring values * Update part API - Add new annotation to PartLocationDetail view * Update API version * Apply similar annotation to StockLocation API endpoints * Extra tests for PartCategory API * Unit test fixes * Allow PartCategory and StockLocation lists to be sorted by 'pathstring' * Further unit test fixes
