Fix incompatibility with ujs

Stop rendering button links inside of forms, instead render them as
links and let ujs handle them normally. This fixes an issue where links
would launch two confirm boxes but not actually hit the correct url when
a confirm was specified due to it hitting two different jquery_ujs event
handlers.
