[Xastir] Online open maps downloading too frequently

[David A Aitcheson]

Alex,

Change that NWS radar image .geo refresh rate to 360 seconds (6 minutes)
as that is how often the NWS refreshes.  That should solve most if not
all of your problems.

Every time the radar image refreshed, it triggered a refresh of the OSM layer.  That resulted in a download/cache test every minute.
