#108 do not set border attribute on table element

[Alan]

Currently the HTML writer sets border=1 on the table element. Setting this attribute might be considered a bug, since setting the border attribute cannot be overridden by styling the table element (with CSS).

This is a styling decision, and should go in the style sheet. Possible approaches are discussed here:

This is a question of aesthetics and practicality, not a bug.
