Moved from Compound to Americano

This version only has the compound -> americano modifications.

That being said, there is bugs that have been fixed in the "full featured"-PR:

- some "send" have not been changed to "res.send" (they shouldn't appear in code though, untested error cases)
- body fields validation for emails is broken in this PR
- some other very small things I cannot remind exactly but that can break something
