Subject: A couple of Futon improvements:  * JSON strings are now displayed
 as-is in the document view, without the escaping of new-lines and quotes.
 That dramatically improves readability of multi-line strings.  * Same goes
 for editing of JSON string values. When a change to a field value is
 submitted, and the value is not valid JSON it is assumed to be a string. This
 improves editing of multi-line strings a lot.  * Hitting tab in textareas no
 longer moves focus to the next form field, but simply inserts a tab character
 at the current caret position.  * Fixed some font declarations.
