When pressing Activate, if the the tracker does not respond within 90
seconds, please Toast "Tracker not responding".   Currently the
Activating spinbar goes on for a long time (perhaps 3 minutes)?
If user presses on red label in Map screen, popup should say:  Tracker
data older than 5 minutes.  Update?   If user presses yes, then
t030s001n123456 is sent (as before).  However, if the tracker is also in
Continuous mode (something obviously went wrong for receipt to be older
than 5 minutes), the app also needs to send a txxxs***n123456 after the
t030s001n123456, where the xxx was the interval specified for that
tracker.
