[Biopython] SPARK error messages to be sent to stderr?

[Uri Laserson]

The spark error messages when there is a parsing problem are currently
getting sent to stdout:

(line 181 in Bio/Parsers/spark.py)
print "Syntax error at or near `%s' token" % token

Can this be changed to:
print >>sys.stderr, "Syntax error at or near `%s' token" % token

This way the error messages can be handled separately.

Thanks!
Uri
