Bug with folders and up/down

[David Bellows]

With folders turned on and choosing either Single/Versus or Couple which 
brings up the song selcting screen, if I choose up or down ("i" or "k" on the 
keyboard) first, without hitting the left/right buttons first, the game 
crashes with the following output:

Traceback (most recent call last):

    self.player_diffs[ev[0]] %= len(self.current_song.diff_list[gametype])
AttributeError: SongSelect instance has no attribute 'current_song'

If instead I choose left/right ("j" or "l") then the game functions perfectly 
thereafter allowing me to up/down ("i"/"k") at will.  Again, only if up/down 
is done before left/right and the folders option is on, does the game crash.
