AltF4 c8ac6cfce8 Add support for Java's Random() class PRNG
- This commit has a lot going on, since Java's PRNG uses signed
  64 bit seeds. Blah! So we changed a lot of plumbing to support
  that. That's why so many files were touched.
- Added -s and S flags to support manual specification of seeding
  ranges.
- Also added support for Java's bounded random. IE: nextInt(int)
