Fix bug wherein the wrong methods were being shown for each controller
Implement filter-centric search

Allow users to search for all actions that skip (or use) filter X

ApplicationController.actions_using_filter(:require_login)
ApplicationController.actions_skipping_filter(:require_login)

These calls return a Hash structured as followed:

{Controller1: [:action1, :action2], Controller2: [:action1, :action3]}
