be smarter again .. and encode the size of the popup in the className :)

<a href='....' class='popup_640x480'> ... </a> automagically makes this anchor been open as a 640x480 popup !
without toolbars and stuff, for the equivalent of target='_blank' just use class='popup'
class='popup2' is used for fiche.php (and fiche.php olny)

I plan to rename popup2 popup_f or sth like that. maybe... one day. it's cool atm
