Display rank-up vote winner on the post-voting upkeep screen

The post-voting (deep_upkeep) screen now names who won the rank-up vote
and their new rank, instead of just "Voting complete!". Adds
Game.last_rank_up_player_id (+ migration), set when votes are tallied
and cleared when the next scene begins; falls back to a "no one ranked
up" message when there were no votes.
