link to tags from tag column in main view

Hi, I have added a link to the TAG column to filter directly with the tag, that's handy for me...

here is the diff for 2.0rc4 (might need some cleaning ;-)
diff function_table_html.php.orig function_table_html.php
1508a1509,1510
> }elseif ($key == "Account info: TAG"){
> $data[$i][$num_col]="<a href='index.php?".PAG_INDEX."=visu_computers&filtre=a.tag&value=".$value_of_field."' >".$value_of_field."</a>";
