Build 3.5.0.128 of xlsgen fixes a limitation in 64-bit scenarios.

Some of what xlsgen used to have since last november (2014) for avoiding out of memory exceptions while loading large files when it crosses then 2GB limit, was actually also compiled for 64-bit scenarios even though in 64-bit cases a process can hold more than 2GB of memory (physical or virtual).

So this build undoes the unnecessary 2GB check in 64-bit, and as a result scenarios can eat all the memory you have (physical or virtual).
