1. *correctly* fix the printing of size_t variables. Need to do this through a #define, not just typecast things. Thanks to Jeff/Brian for suggesting a cleaner way to do it (as opposed to just doing the #define at the print location). Note that not ALL of the prints have been "fixed" yet - will continue to identify them.
2. Add int64 and size_t to the pack/unpack unit tests.
3. Fix a bug in the int64 pack/unpack system.
