Allow Game::savestats() to accept a pointer to ScreenSettings

Another step to fix the bug #556 is to allow Game::savestats() to accept
a pointer to an existing ScreenSettings struct. This entails refactoring
Game::savesettings() and Game::serializesettings() to accept the
function as well, along with adding Screen::GetSettings() so the
settings of the current Screen can be easily grabbed.
