Add ability to sort courses and clear filters (v2)

[ap-1]

Adds the ability to sort courses on the search page by several heuristics at once. These currently include FCE, TeachingRate, CourseRate, CourseNumber, and Units, the first 3 of which are disabled unless the user is signed in. Each heuristic can also be assigned Ascending or Descending.

The user can drag and drop heuristics (called "sort options") to set their precedence for sorting, and press on its respective pill to toggle between Ascending and Descending. The goal is to allow the user to do things like prioritize low FCE courses with high ratings, prioritize high unit courses that are low in course number, etc.
