Crash when using KeyValue.loadAsText() with local appinfo file.

[LossyDragon]

Expected Behavior

Should be able to parse a local appinfo vdf text file into KeyValues.

Actual Behavior

This is probably due to the local file not being read with UTF-8 encoding.

Exception in thread "main" java.lang.NullPointerException: Cannot invoke "String.startsWith(String)" because "s" is null

Steps to Reproduce the Problem

1. Call SteamApps.picsGetProductInfo() with metadata true
2. Locally download the .gz file and extract the text file
3. Call method KeyValue.loadAsText()

Sample App

public class TestKV {

    public static void main(String[] args) {
        KeyValue kv = new KeyValue();

        // AppID: 1938090
        // http://clientconfig.akamai.steamstatic.com/appinfo/1938090/sha/<App's_SHA>.txt.gz
        KeyValue.loadAsText("....");

        printKeyValue(kv, 1);
    }

    private static void printKeyValue(KeyValue keyValue, int depth) {
        if (keyValue.getChildren().size() == 0) {
            System.out.println(keyValue.getName() + ": " + keyValue.getValue());
        } else {
            System.out.println(keyValue.getName() + ":");
            for (KeyValue child : keyValue.getChildren()) {
                printKeyValue(child, depth + 1);
            }
        }
    }
