In LogFormatter:

In LogFormatter:
* Changed LogFormatter to support displaying redacting log items if the context user can see them. The default mode is still "show only public items".
* Fixed static calls to non-static getRestrictedElement() function.
* Cleaned up LogFormatter that build up vars only to then throw them away and replace them with rev-deleted placeholders.
In RevDel_LogItem:
* Use LogFormatter instead of raw LogPage::actionText call as such calls are broken and just displayed things like the string "move" (the log action name) instead of "x moved a to b: reason" and such. Fixes r96546.
