2.5.4 Sort student lists

1. #101: Added sort/filter functionality for lists to allow advisors to easily sort and filter their lists of students, but this functionality also applies to other lists in the system. Student list sort/filter is currently as follows:

• Name and Student ID columns can be sorted and filtered
• Status column cannot be sorted or filtered YET (we are working on this for the next release!)
• Cohort column can be filtered (sorting is not possible for this column)
  To sort a column, click on the column header once. To sort it the opposite way, click on the column header again.
  
  To filter a column, start typing what you want to filter to in the box above the column you want to filter by. To remove the filter, delete what you typed in the box.
  

2. #99: With the retirement of CTools, we have adjusted the help text for the weekly activity visualization to remove mention of CTools.

3. #112 #108 #115: Changes to handling of lists and list items to make the sorting/filtering work.
