Case sensitivity option is not applied inside lambda expression

[ealeykin]

Case sensitivity option is not applied inside lambda expression:

var interpreter = new Interpreter(InterpreterOptions.LambdaExpressions|InterpreterOptions.DefaultCaseInsensitive)
    .SetFunction("Now", (Func<DateTimeOffset>) (() => DateTimeOffset.UtcNow))
    .SetVariable("List", new List<DateTimeOffset>());

interpreter.Parse("list.Any(x => x > now())");

Will parse list but then throws Unknown identifier 'now' (at index 5)
