New filter for list_cats() $exclusions variable

[Alex Parkhomenko]

Could we add a new filter to give plugins more control of categories selections from database without modifying a template?

Would be useful in multiauthor views and category detections by browser-requested language.

This patch looks to add a filter right after this bit:

$exclusions = '';
        if (!empty($exclude)) {
                $excats = preg_split('/[\s,]+/',$exclude);
                if (count($excats)) {
                        foreach ($excats as $excat) {
                                $exclusions .= ' AND cat_ID <> ' . intval($excat) . ' ';
                        }
                }
        }

in order to adjust which categories get exluded. Such a filter could conceivably prepare a complex exclusion list (exclude all categories owned by users X and Z but not Y).

Adding filter and action hooks is cheap.
