integrate game_board into turn_info object

This commit manages to purge all references to resources::teams
and resources::units from the turn_info object, by moving
functionality to game_board, or refactoring to use const &
accessors.

This is not a strict refactor, but I had my hand in the earlier
state of this code anyways, and I have playtested the new version.
