I decided that translations in 3 forward or in all 6 frames is common enough
request to have them in bioperl. To not change sequence interfaces, I added
the two methods into Bio::SeqUtils.

 #takes the same arguments as translate (frame naturally ignored)
 @seqs = Bio::SeqUtils->translate_6frames($seq);
