(Bug 2174) Reading filter options: public/order

[foxfirefey]

This is my very first Github pull! Basically, I saw somebody with some very good criticism about long standing reading filter bugs, and when I looked over it, turns out those capabilities were in the backend and just needed a little hooking up with the current front end. Best part is it also takes care of Bug4501--efficient! Booyah:

See previous pull, discussion/responses to constructive criticism about subscription filter. Putting a version of long roadmap comment here for notekeeping.

Notes: Transmogrified fixes to do

[foxfirefey]

* Transmogrified should use the appropriate color for the titles in the modules, instead of the link color, for headers that are links
* Report of a theme--probably Shallowest Depths--that has a link visibility problem on the entry page
* Investigate aligning the top edges of the side bar nav and the main content as well in Transmogrified.
