Tons of work

This is about as far as I want to go before 1.7, so I figured I would pull it now. I'd also like for you to be able to help update to 1.7

Changes:
- Ton and a half of bugs fixed
- Mistcloak Item. Made with wool, gives bonus speed.
- Lots of tweaks to textures
- Miscellaneous tweaks (Iron/Steel stopping fall damage, Moving item and block registry to it's own class, config, etc)
- Update to ForgeGradle
