getRandomWord(n) only returns words of length n

[Bathlamos]

At line 503 of DataFactory.java, the following method

    public String getRandomWord(int length) {
        return getRandomWord(length, length);
    }

should be

    public String getRandomWord(int length) {
        return getRandomWord(0, length);
    }

this is the same as issue #8
