New network page, Part II

We have had a lot of great feedback about the new network page. As a result, we:
  1. Added a header row to make things more clear
  2. Made it so clicking the headers will sort by that column (clicking the headers again will reverse-sort)
  3. Set it to save your sort preference (does not apply to other peoples networks...)
  4. Added a link to "Show All" and back to "Normal View"
  5. Added a link to "Who Lists Me?" and back to "My Network" (when viewing "Who Lists Me?" the green circle indicates who you list as a friend)
