[Plugin: WP-dTree] Feature request: include with tag

I have seen other widget plugins that allow you to include them within a post or a page by using a tag like [pluginname:options]. I think it would be useful if WP-dTree has this ability so one could create more custom archive or category indexes.

Ideally some of the options could be archives, links, categories, pages, feed, expandall, expand(categorynumber), and postcounts.

Personally, I would use this to create an index page that listed all my categories, their post counts, along with their feed icons and have one of my categories expanded by default.
