Stamina For Tweakers

Fixed

• Use getAttributeValue() instead of getAttributeBaseValue() in several places so that modifiers work correctly.
• Use Double.compare() in a couple of places where precision issues were causing weirdness.
• Fixed a race condition which could cause the config to lose effect configs.

Changed

• Lots of refactoring of the config system under the hood to make default config handling and rule reloading on config change much, much simpler.
