In-file inline translations

[nandoAlbertengo]

Allow to specify the translations inline:

<!-- Panini-processed html template -->
<p> ${{template.common_use_case_text}}$ </p>

<!-- This came from a Partial -->
<p> ${{en: "Hi" | es: "Hola" }}$ </p>

This would allow edge cases like mine, where i have partials that must be translated too but after Foundations Panini joined them into the soon-to-translate template, effectively losing its original reference to its translation file.
