Address player list review feedback

- Rename the player table element data class to element_data
- Remove the redundant offline selection clear; on_player_left_game
  already clears any selection pointing at a player who disconnects
- Move the action bar and reason bar visibility into their own refresh
  methods so refresh_player just delegates to them
