* simplify render helper
* Follow up #2133
* og:type is only accounts/show
* revert accounts/{following,followers}
* Add routing specs for accounts followers and following actions
* Use more restful route naming for public account follow pages

- accounts#following to accounts/following_accounts#index
Adds routing spec to ensure prior URLs are preserved.
