function _vppr_page_taxonomy_overview in Vocabulary Permissions Per Role 6

Page callback for taxonomy overview.

Displays the form core ships if $user has 'administer taxonomy' permission, or a simple list that mimics the same otherwise. Rationale: don't display even a stripped-down form if we don't need a form but only a nicely-formatted list.
