Fixed Gamelog memory leak

Yeah, so there was actually a memory leak that I attempted to fix by
straight deletion. However, I found that attempting to delete the new
character array that I had made caused a heap corruption error.
Turns out that I had misinterpreted the initial incoming array as having
a '\0' at the end where, in actuality, it does not. So, I've increased
the size of the new array I use to append the characters by a single
byte and now all is well.

I do love looking at memory step by step.
