[PATCH v2 19/20] nmbug-status: Escape &, <, and > in HTML display data

'message-id' and 'from' now have sensitive characters escaped using xml.sax.saxutils.escape [1]. The 'subject' data was already being converted to a link into Gmane; I've escape()d that too, so it doesn't need to be handled ain the same block as 'message-id' and 'from'. This prevents broken HTML
