v6.1.0b - WPS optional

6.1.0b
 * Add user selection of WPS as define USE_WPS in user_config.h in preparation for core v2.4.2 (#3221)
 * Change default Wifi config option from WPS to Wifi Manager if WPS is disabled (or Wifi Smartconfig if webserver is disabled)
 * Remove WPS from sonoff-minimal saving 33k code space
 * Revert wifi changes implemented in v6.0.0a due to possible bad initial wifi connections
