[Suggestion] Preferred position and role information

[talhak]

I think IRL most players do have their own preferred position and role such as the preferred side as central positions, player traits, etc. So it would be useful that we will be able to see this information on player profiles. I think it is already implicitly implemented since we have already an option such as "Will play his preferred position and role" when we try to persuade a player who has doubt to join the club we manage.
