* Major changes to OrePopulator to support any material based simply on config (currently has a tendency to throw a StackOverflowError when trying to use Sand in the Nether as it attempts to process physics while placing, strangely doesn't affect the end)
* Add global damage modifier support and an implementation of modifier to NetherHandler
* Modify the WaterCollisionTask so its damage rate is more inline with the speed lava damages players but also change the underlying damage to be affected in the same way as lava (i.e. reduced by armor)
* New format for ores in config.xml to match the new, more flexible code in the OrePopulator
! TODO: Fix the underlying cause of the StackOverflowError. Won't do it now as I need sleep
