[BioPython] aligning with clustalw fails

[Gregory Singer]

I replied to Karin personally about this, but I suppose I should have sent my
message to the whole list. In any case, the problem can easily be fixed:

Update the regex in line 31 of Bio/Clustalw/clustal_format.py to:

Martel.Re("[-a-zA-Z:;^_'\",\#\|\[\]\(\)\/\.\d\+]+"))
