Individual Legacy Hook Mapping
Change the "enable legacy hooks?" option
It would probably be best for performance and flexibility if admins could select exactly which legacy hooks to activate in special hooks, if any at all. Currently enabling legacy hooks activates all of them, and 1 or 2 may have conflicts with showwiki.php, or maybe only 1 or 2 are desired.
It should be possible to use a multi-select field in VaultWiki options.
