This feature will attempt to make an http connection to the URL specified. If it fails, the current AP will be marked disabled and disconnected from.

With this option you can force the app to only start a re-connect according to priority if the current connected network's signal level is below a certain value. To get the old behaviour, just set this value to 100.

An ongoing notification will be displayed to allow the service to run as a foreground application. This will protect the application better from low memory kill by the OS. Obviously this option can be switched off.

I've noticed that Android don't scan for new wireless networks often. I'm going to add an option to force a network scan every time the prioritizer job kicks off. 

The application will have the ability to exclude selected WiFi networks from the auto switching mechanism.

The application will periodically switch on WiFi if it's disabled, scan for new networks and if a pre configured network is available, connect to it and leave the WiFi connection on.
