* use encoding/json for comment parsing * refactor by moving loop code to an UnmarshalJSON * use a preallocated array and indices to maintain order while using goroutines again, this was removed a while ago * use new struct in comment.hbs and contextComment.hbs * rewriteUrl partial to reduce rimgo-specific code in api * move RenderError into pages package to avoid import cycle between render and utils
