Title: Wifi enabler

This is a utility that periodically (via brewpi cron.d file) checks to see if the wifi connection is still up by checking for a default route and pinging the router. If this fails, it will attempt to restart the wlan0 interface, saving the user from having to restart the Pi manually (or connect monitor/keyboard, etc)
