[webservices] All DMC web services are available with updates to ws-station and ws-event

[Chad Trabant]

Hello web service users,

The IRIS DMC's web services are now all available.  Please let us know if anything is not working as expected.

The database migration was successful, for service users you should notice no difference except maybe a speed boost for reqeusts that use the database.  

While all the systems were down we took the opportunity to update the ws-station and ws-event services.

Update for ws-station:
  * Unprintable characters are removed from the site field of the text output (newlines, carriage returns and nulls).

Updates for ws-event:
  * Fixed a bug resulting in a "null exception" when asking for events updated after certain time.
  * Fixed a bug causing missing magnitudes when "eventid" input parameter is provided.

thanks,
IRIS DMC Web Services Team
