main: Deep sleep after network failures 

Instead of entering a "hot" reboot loop when there is a problem
connecting to WiFi or the MQTT broker, the chip will now go into deep
sleep for a minute before trying again.  This should conserve battery in
situations where simply trying again right away won't fix the problem
(e.g. WiFi is actually down, or the band conditions are just really bad
for now).
