* Fixes#2680: Use a shorter cable anchor model when blocked by a facade.
* Fixes#2664: Prevent anchors from creating intersection.
Replaced the simple List<ResourceLocation> for the static models with a
new container also indicating a solid part, which can be used to prevent
the creation of an intersection.
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.
Reduces the visibility of all fields to private and create setters/getters
when necessary. Exceptions are fields with GuiSync as these need to be
public.
Reduces the visibility of internal methods to private/protected/default when possible.
Deprecates the old usage of the AEItemDefinitions via the direct method access of
* blocks()
* parts()
* items()
* materials()
and thus use the new re-direct via definitions().
All definitions are now initialized, no matter what. But SubItems, Items and Blocks are not registered, if by chance are disabled.
