Use entity_encoding: 'raw' in notes

This (and some other things) will help avoid changes in uploaded notes, which
cause loss of cursor position and other problems after local notes are updated
with the server version.

A side effect is that multiple spaces won't be converted to ` `, so
anything consuming note content will have to use `white-space: pre`.

(Notes in reports appear to be substituting ` ` as necessary,
though I'm not sure where that's happening.)
