Removed ASMTweaker and replaced it with AT. (#2636)

Added appeng_at.cfg and updated build.gradle to correctly include the AT when building.
Deleted the now useless ASMTweaker.
Moved the coremod from package transformer to coremod as a better matching name.
Updated the old 1.7.10 code using reflection to drop it where forge or vanilla now exposes that functionality directly.
