added initialisation to setup so wifi is no longer global and it gets cleaned

dnsServer and webServer are also no longer global

+###Timeout
+If you need to set a timeout so the ESP doesn't hang waiting to be configured, for instance after a power failure, you can add 
+```
+wifi.setTimeout(180);
+```
+which will wait 3 minutes (180 seconds). When the time passes, the autoConnect function will return, no matter the outcome.
+Check for connection and if it's still not established do whatever is needed (on some modules I restart them to retry, on others I enter deep sleep)
+
+###Debug
+Debug is enabled by default on Serial. To disable add before autoConnect
+```
+wifi.setDebugOutput(false);
+```
