Patch: Specific class for each generation.

I needed to style each level in reverse order, so the last (bottom most) pages have the same style (font size, for example), and each level up can be styled differently (larger font size, for example).

Here is an example of the CSS I use:

.posts_wide .list-pages-shortcode a { display:inline-block; text-decoration:none; }
.posts_wide .list-pages-shortcode ul { margin:0; }
.posts_wide .list-pages-shortcode li { list-style:none inside none; padding:0; margin:0 0 0 20px; }
.posts_wide .list-pages-shortcode li .excerpt { color:#666; margin:0 0 5px 30px; }
.posts_wide .list-pages-shortcode li.gen-0 > a { font-size:1em; margin:0; }
.posts_wide .list-pages-shortcode li.gen-1 > a { font-size:1.05em; margin:2px 0 0 0; }
.posts_wide .list-pages-shortcode li.gen-2 > a { font-size:1.1em; margin:4px 0 0 0; }
.posts_wide .list-pages-shortcode li.gen-3 > a { font-size:1.2em; margin:6px 0 0 0; }

And the patch:
