[Plugin: Related Tag Filter] add the option for categories and other custom taxonomies as well

Hi there,

Since we are on version 2.9.2 of WP, with WP 3.0 release being imminent, I was hopping to find a plug-in that would do what this plug-in does, but also to include categories and other custom taxonomies.

Any chance these options should be added to this plug-in? That would be fantastic.
