change the returned value of method [readToken]

[dota17]

When I read the code, I found that the method [readToken] always return the true value.
But in other place, the returned value is used to judge.
For example, in the method [readObject]

while(...)
    initialTokenOK = readToken(tokenName);
if (!initialTokenOK)
    ....

So, it is a mistake for the returned value, I think.
