Sortable lists

[arkon]

Deals with being able to reorder the annotation categories list (issue #80).

Also replaces the mechanism used for rubrics with a jQuery-based one (as opposed to a deprecated Rails method).

@david-yz-liu The test was fixed, by the way (accidentally deleted an end).

Now getting two errors:

test_: An admin on :add_annotation_category should with error on save. (AnnotationCategoriesControllerTest):
NoMethodError: undefined method `+' for nil:NilClass
    /home/david/Documents/Markus/app/controllers/annotation_categories_controller.rb:24:in `add_annotation_category'

test_: An authenticated and authorized admin doing a POST should be able to update_positions. (FlexibleCriteriaControllerTest):
NoMethodError: undefined method `each' for nil:NilClass

@david-yz-liu Those tests should be fine now!

Cool, looks good except the text selection bug that we just talked about.

@david-yz-liu I've prevented text selection and also fixed an issue where dragging again before an AJAX call was complete would break the sortable list.
