v6.8 - Fix for continuous scan - Contact/Motion

An error was occurring after constant scanning for a long time, specifically when (multiple?) contact and motion sensors were included in the device list. The workaround applied will BLE scan for 30 min then stop and immediately restart scanning for another 30 min, instead of scanning indefinitely. This seems to solve the issue and does not affect use.

I have also shortened some json attributes and stop/restart the webserver on MQTT/WIFI reconnect
