Slightly reword i18n.html and i18n-messages.html to reference apps.
Instead of putting 'extensions or apps' everywhere,
I did my best to make the text speak for itself without that repetition.

Aaron, this is an example of shared apps and extensions content
that in the long run might be better in a centralized set of docs.
