Update recipes

This is an unfocused set of changes, I hope that's not a problem since it's only of the docs anyway.

I updated code which has changed in the meantime, converted 4 space indentation to 2 spaces, unified templates & views directory structure (thanks to @austinpray for suggestions), removed blockquotes from step descriptions because they weren't quotes and removed other random oddities.

I probably missed some things, I'll do a double-check later.

Fixes #237, #203.
