[webservices] Unreadable file format for miniseed data from web services

[Doug Neuhauser]

I've posted current version of
	qmerge
	sdrsplit
	qlib2
to:
	ftp://www.ncedc.org/pub/quanterra/ucb/qmerge.2011.046.tar.gz
	ftp://www.ncedc.org/pub/quanterra/ucb/sdrsplit.2011.046.tar.gz
	ftp://www.ncedc.org/pub/quanterra/ucb/qlib2.2011.046.tar.gz

Let me know if this does not address your problems.
