Changes for version 2.0:

• Increase portability by targeting C99 language standard instead of Microsoft standards.
• The extended integer size grows dynamically. One executable is all that is needed now.
• Removed the assembly language code.
• Helper file irreducables.bin is no longer needed. It is now generated in memory at startup.
• Removed source code loop unrolling. Compilers can do this now if needed.
• Remove inline function declarations. The compiler can inline functions when appropriate.
• Optimized C language highestSetBit function.
• Added SSE (128-bit per loop) shift function.
• Fixed bug where bad factor files were flagged only in verbose mode. Bad files are now deleted.
• Revised factor files. Some were incomplete.
