[webservices] Update to the DMC's FDSN station metadata service

[Chad Trabant]

Hello web service users,

We have updated our FDSN station metadata service to fix a minor bug:

http://www.service.iris.edu/fdsnws/station/1/

Returned results were improperly limited to stations that belong to a virtual network (most do), now all stations are included in the search.  Because most stations belong to at least one virtual network, the impact of this bug was expected to be minor and the fix should not affect the general use of this service.

regards,
Web services team
