Alchemy translation methods

Instead of having to translate strings and defining a default value:

Alchemy::I18n.t("Hello World!", :default => 'Hello World!')

We define this method to define the value only once:

Alchemy::I18n.t("Hello World!")

Note that interpolation still works:

Alchemy::I18n.t("Hello %{world}!", :world => @world)

It offers a shortcut method and view helper called _t

Notes

All translations are scoped into the alchemy namespace. Even scopes are scoped into the alchemy namespace.

So a call for _t(‘hello’, :scope => :world) has to be translated like this:

de:
  alchemy:
    world:
      hello: Hallo
