New feature parameter: categorymatch
The third-party-version of this addon (found here) supports the very useful parameter categorymatch. On my wiki, this is used to collect articles from categories with similar names. After switching to the Intersection-Addon, I missed this feature. so I added it myself. Maybe other users are also interested in this, so here is the udiff for DynamicPageList.php
Usage:
<DynamicPageList> category=MustBeExtended categorymatch=%fruit%|%vegetables% notcategory=electronics </DynamicPageList>
This will find any aticles in categories with names like fruit and vegetables which also are contained in the category MustBeExtended.
