FEATURE: Implemented new types of Wifi SmartConfig

[P-R-O-C-H-Y]

Summary

Implemented all types of Wifi SmartConfig.

Function changed from:
bool beginSmartConfig();
to
bool beginSmartConfig(smartconfig_type_t type = SC_TYPE_ESPTOUCH, char* crypt_key = NULL);

If WiFi.beginSmartConfig(); is called, ESPTOUCH is used as default type.
Or you can specify type nad crypt key (used for ESPTOUCH_V2 only):

char crypt_key[] = "ESPWIFISMARTCONF"; //should be 16 chars lenght
WiFi.beginSmartConfig(SC_TYPE_ESPTOUCH_V2, crypt_key);

SmartConfig types	Protocol used
SC_TYPE_ESPTOUCH	ESPTouch
SC_TYPE_AIRKISS	AirKiss
SC_TYPE_ESPTOUCH_AIRKISS	ESPTouch and AirKiss
SC_TYPE_ESPTOUCH_V2	ESPTouch v2

Impact

New types of WiFi SmartConfig supported.
