Sort Resources UI

The consensus is that we'll use concept from the following mockup: http://www-personal.umich.edu/~jimeng/Sort3.html

We'd also like to include an interface for screen readers that is somewhat hidden from sighted users that is a drop-down menu of integers.

As for getting to this interface, we'll be adding another link - Sort - to the Resource action column.

We'll need a working Javascript/HTML model by Sept. 11 is the latest.
