Adding true I18n support

[shushugah]

Would there be interest to add I18n support to the rails guides? I noticed in the English guide

<%= form.text_field :picture %>

and in the German guide and

<%= f.text_field :picture %>

this may not be a big deal to an experienced developer, but it can lead to a frustrating experience for the students and extra maintenance work.

I think the other benefit asides from streamlined translation, is genuine maintenance/improvements to the docs from more eyes.

If there is interest, I would be happy to start working on this, as an experimental feature, until all bugs/pages are sorted, and I could start writing tasks for others to contribute to as well.

I'm not entirely sure what the proposal is to add i18n. To translate the app's form elements?
Or to make sure the same variables names are used, form vs f?
