annotate db/migrate/029_create_wiki_contents.rb @ 599:251b380117ce feature_227

Introduce a new latest_downloads plugin to manage active and shortcut for attachments.
Add a table for attachment active/shortcut data.
Move existing active-handler code into the new plugin (but still using the "old" active column in the attachments table).  Note the files_controller stuff doesn't actually work here.
