Restore the link to edit trove categories, was accidentally(?) removed in
git show b55760a -- Allura/allura/templates/user_skills.html
trovecategories.enableediting from simply boolean to allow an option for admins only to edit. It should be a link on the /nf/admin sidebar
Add events (via
g.post_event) for every category add/remove/edit, so that 3rd-party code can listen for those changes (e.g. to keep another database in sync).
