Use normal ascii quotes and apostrophes in code examples

[mdaniel]

In the simple api section of the website, the code formatting(?) is converting the double-quotes to ” (ironically enough, not 201f for the opening quote) and the apostrophes to ‘ and ’ in the code snippets.

This stops users from copy-and-pasting the examples into their terminal or their editor, along with looking out of place with the rest of the fixed-width font.
