Auto-hide remote locations that haven't checked in in a while

[GoogleCodeExporter]

WPT has a great feature that automatically hides devices that haven't connected 
in a while, to keep them from accumulating a large backlog and frustrate users. 
Relayed locations don't benefit from that, and will show as live even if 
they've been dead for a while. 

The auto-hide functionality should be expanded to include relayed locations.
On a similar note, the "time since last check" for relayed locations should 
also be available through the checklocations.php and other scripts to allow 
users of the API identify a location is inactive too.

Implementation note: Periodically in the getwork.php cron support we should 
connect to all remote locations and fetch the "last check" information and 
populate the local .tm files.  Everything else should automatically work once 
that is in place.  

Update frequence does not need to be more than every 15 minutes since the 
threshold is 30-60 minutes but it wouldn't be a bad idea to do it a little more 
frequently (say every 5 minutes).  We could potentially grab the backlog at the 
same time so we can provide some feedback on overloaded locations.
