v2.0.0

The first version of this package featured some possible infinite loops, mostly while waiting for a wireless interface to adopt certain properties. Those loops have been replaced with timeouts which can be configured with the new setting parameter connectionTimeout (in units of ms).

Code has also been refactored so each OS has its own file.

This version is incompatible with the previous version, as WiFiControl.connectToAP( _ap, cb ) and WiFiControl.resetWiFi( cb ) are now async methods.
