- Refactoring Randomizer so it's not a singleton
 - Randomizer still has the same flaws as before WRT multi-threaded programming, but removing the singleton is step #1 to fixing any issues
 - Removing generateSalt from Randomizer (do not know why this was put there in the first place)
 - Making it so that Randomizer is little more than a template interface to a RNG
 - In general, I must look at removing a lot of the singletons
