Changed translate helper so that it doesn’t mark every translation as safe HTML. Only keys with a "_html" suffix and keys named "html" are considered to be safe HTML. All other translations are left untouched.

Added partial scoping to TranslationHelper#translate, so if you call translate('.foo') from the people/index.html.erb template, you'll actually be calling I18n.translate(people.index.foo) [DHH]
