Bug [graph]: fix word wrapping in on-node fields

[alex-mashin]

In graph format, non-page property values that are displayed on nodes (with graphfields = yes) should be word-wrapped with <br />, not newline, since they are displayed within <td> HTML tags.

Shouldn't we implement this with CSS instead of hard-coded line breaks?

As far as I understand, there is no way to automatically word-wrap in dot, including HTML-like strings, neither in SVG with CSS.

If you know a way, please tell us.
