Jonas Thörnblad 6ca64526bb Fix handling of RNG seed 
* Fix truncation of output seed value from 64 bits to 32 bits (int
  instead of uint64) when written to json file.

* Fix input seed value conversion when --seed option is used.

* Remove input seed value scrambling (use of rngseed()) when --seed
  or --randomize-seed option is used since the output seed value will
  be the scrambled value and not the seed that was actually supplied
  or generated.
