Updates to Rails 4.1.2
Updates to use mislav/will_paginate from master

The `count` method is finally fixed on the master branch, but the current version of `will_paginate` on RubyGems (v3.0.6) still doesn't have everything needed to make `count` work. So switching to mislav/will_paginate from nazgum/will_paginate, but still waiting for an updated version of the gem.
