Compliance helpers

@fancyremarker  This, depends on #14 first

The main idea here is to generalize some of the helpers inside dashboard so they may be used in the compliance apps.

What do you think about the change to `register_url` inside view_helper.rb?  This allows all apps to share common header partials without defined routes for orgs/users.


Cool.  I'll move these to the Controller module.  There will be places that we'll need to specify a user ID, e.g. linking to a security officer's profile page.  I'll default the method to using current_aptible_user.id if one isn't provided.
