<admin suggestions> changes for visual testing

Conflicts:
	admin-console/app/views/admin_console/suggestions/_generic.html.haml
<admin suggestions> parse config "none" thresholds
<admin console> max active gears uses effective available
<suggestions> extract types to lib; clean up rails autoloading

"require"ing something under Rails autoloading lands us in a heap of
trouble. Pulled all of the value objects into two files in controller
lib/admin/suggestion, then made everything else load based on
namespace constants.
<admin stats> refactor, fix rails autoloading

Admin::Stats is now Admin::Stats::Maker
Admin::Stats::HashWithReaders and subclasses are in admin/stats/results
There's no "require 'admin/stats/maker'"
This should help with Rails (re)loading Admin::Stats
<admin suggestions> move advisors to separate namespace

Admin::Suggestion::Capacity::Add was a value object.
Admin::Suggestion::Capacity::Add::Advisor was an advisor.

Loading the first could keep the second from auto-loading.
So, moving all of the advisors under the namespace:
Admin::Suggestion::Advisor, e.g.
Admin::Suggestion::Advisor::Capacity::Add which creates objects of type
Admin::Suggestion::Capacity::Add*
(value objects are not changing namespace, just advisors)
Sort suggestions by important and type
