Incorrect return type in SoftwareSerial.listen() reference page

[per1234]

https://www.arduino.cc/en/Reference/SoftwareSerialListen says:

Returns
None

but actually it returns a bool:
https://github.com/arduino/Arduino/blob/1.8.3/hardware/arduino/avr/libraries/SoftwareSerial/src/SoftwareSerial.h#L95

bool listen();

Updated and pushed the Reference page with
"Returns
boolean: Returns true if it replaces another"
