Issue #1629 - Part 5: Remove pointless local variables.

Since the local variable is always initialized to false, we don't actually need to declare it and can just pass "false" directly as a parameter to the PrepareSheet function's bool. I was worried about code readability at first, but some well-placed comments took care of that.
