Fixing up the admin panel

1. Removed irc commands in susers for both mod and admin
2. Fixed up /admin/irc and admin/commandlog
3. removed blog entries from admin since blog is no longer used
4. fixed a use case where a user could be an admin but not a mod and it would not give acces to the mod commands that admin inherits
