Better handling of wifi disconnect (#231)

Browse Source 
When network interface is down, some nasty things happen, for instance tcp_connect returns without ever calling error callback.
This change adds some workarounds for that: before doing a tcp connect and DNS resolve we check if there is a route available.
Also added a listener for wifi events which stops (aborts) all the WiFiClients and WiFiUDPs when wifi is disconnected. This should
help libraries detect disconnect properly.
