Add height/elevation info

[dlnorgaard]

When hovering over a station in the map, the lat/lon displays but not the height. Jeremy requested that the height info be added.

Height information for FDSN will now display. Data from seedlink does not seem to return location info (or maybe the client is not handling it since there are lots of channels). As for WWS, the height information is not returned in the metadata. This requires further investigation and potentially a change in Winston code.

Opened Winston issue usgs/winston#71 for this.

I don't think there's a way to add height to the GETCHANNELS command without breaking existing clients. You spotted the problem, an exact match on argument count in Channel.parse(). That's no good.

However, instrument height is returned by the GETMETADATA command. I'm closing this for now. If GETMETADATA won't work for you or if you have an idea for accommodating height in GETCHANNELS, re-open the ticket.

GETMETADATA INSTRUMENT may not work for some Winstons installed after following bug was introduced: usgs/winston#78. Awaiting fix before proceeding.
