Don't escape quotes ('/") in text nodes and attributes.

- In text nodes quotes are fine
- In attributes quotes are fine if used reciprocally.

Escaping in the latter case often causes issues, e.g. with quoted font names (#21) or inline CSS styles (#56), while it probably does not gain anything (if quotes are wrongly used in attribute names the XML is most likely invalid to start with)
