RC04 - Patch 0002

Changelog:
 - Renamed LuckContainer#baseValue() to getValue()
 - Changed the way files save by using the Map#values() call instead of iterating the kvp's.
 - Made the actual percentage rng value round to the closest whole number before being checked.
 - Changed Luck#defaultValue() to getDefaultValue().
