Suggestions about tidy and wml 2

[Denis Barbier <barbier@imacs.polytechnique.fr>]

hi again,

it would be nice to add `summary' attribute to <table> whenever possible
in order to make tidy quiet (and also because it is good practice ;)).
For instance, all template/debian/*bar.wml may be updated.

WML 2 has a scary support for XHTML, and removes trailing slash in
attributes, which is unwanted when this slash is part of an URL.

I made a patch which is quite big (58KB) so i put it here:
