Make table descriptions line break

[odscjames]

In field descriptions textwrap.wrap is used.

So we could also use it in table descriptions?

  table_comment_html = '<BR/>\n'.join( textwrap.wrap(table_comment))

In _graph_add_table - use that when making html_row0 instead.

That does give you multi line and shorter descriptions, but it highlights a problem that the width of the table seems not to fully match to the width of the text inside it. Tweaking width option to the 2 uses of textwrap.wrap changes the width of the table but it's always a bit wrong. Need to look into that more.
