PlayGetDigitsResult is not Success when no digits is provided by user

[tdragon-fp]

Is there any particular reason why property Success in PlayGetDigitsResult is set to false, when there are no digits provided by user and PlayGetDigits is run with MinimumDigits option set to 0? According to the FreeSwitch documentation, 0 is valid value for play_get_digits app parameter. Current behavior is misleading, suggesting something went wrong, when it does not.

That may be an invalid assumption made here:

NEventSocket/src/NEventSocket/FreeSwitch/PlayGetDigitsResult.cs

Line 20 in e29e5f0

Success = !string.IsNullOrEmpty(Digits);

I will take a look at this.

Getting deeper into the problem I think it should be handled similar way it's done in ReadResult, by reading read_result variable:

NEventSocket/src/NEventSocket/FreeSwitch/ReadResult.cs

Lines 17 to 30 in e29e5f0

	if (eventMessage != null)
	{
	Digits = eventMessage.GetVariable(channelVariable);
	var readResult = eventMessage.GetVariable("read_result");
	Result = !string.IsNullOrEmpty(readResult)
	? (ReadResultStatus)Enum.Parse(typeof(ReadResultStatus), readResult, true)
	: ReadResultStatus.Failure;
	}
	else
	{
	Result = ReadResultStatus.Failure;
	}
	Success = Result == ReadResultStatus.Success;

It seems play_get_digits sets this variable the same way, although I cannot find anything to confirm that in FreeSwitch documentation.
