- permission trace correctly uses language variables now

- updated documentation for the auth class
- use cache for "SELECT forum_name FROM phpbb_forums WHERE forum_id = X" queries everywhere and not only in functions_display
- updated the permission trace to include information about global settings overwriting local ones
- take global permissions into account for local permission results on the view permission pages for users
- only allow to change the post author with m_chgposter
