[BioPython] Checked in Parsers for Phred and Ace files

Okay, okay, I changed it back to Phd.py :-). My thinking was that
Phred was a little less cryptic than Phd, but if it results in more
confusion then it helps -- I'm all about achieving maximum consensus.
Harmony. Harmony.

But, seriously, it doesn't fit into SeqIO. That is something that
Andrew started on a while back but really hasn't got much momentum
behind it since than. Frank's code fits more into the standard
Biopython framework of parse what you've got and get the data out of
a Record object.
