Version 0.85 changes include:

#1. 2x - 4x faster than version 0.83 depending on the calculation
#2. RAM usage has been cut in half.
#3. Input calculation has been redone yet again. Due to bit packing, multiples of 64 are now used.
#4. Available search ranges have been raised significantly.
#5. Program will exit after 3 failed attempts to allocate memory for the calculation. If it exits, it means that there wasn't enough RAM available.
