Rename ItemHelper to ItemStackUtils
Change the way OreStack identifies an OreStack from a list of itemstacks. Resolves#923
Added some more test cases to VanillaTestSuite
Added back in the small and medium sized Alchemical Chest aludel recipes
Added a recipe to make a chalk block from 4 pieces of chalk
Created an EE test suite to test EE specific energy values
Re-registered several EE items
Removed a duplicate Gson type adapter registration
Changed the ItemStackSerializer to return JsonNull in the event that there is no registered name for the item (the item would never deserialize as it wouldn't have a name to lookup)
Changed the EnergyValueMapSerializer to allow serializing of null energy values (as JsonNull). Used for energy value testing.
