Major changes! Version 1q release?

Made major changes to project structure. Updated development environment
to ForgeGradle 1.6.4-964. Updated Tinker's Contruct API to 6.0.0 (with
minor manual tweaks). Added access transformers to fix variables
specific to ClayBucket and IguanaItemSkull. Corrected all major IDE
errors in code preventing compilation.

Tested against Tinkers Contruct 1.5.4, pretty sure everything works.
