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.
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.
To integrate these into the current system, some changes to the background had to be done, especially to the feature handler. It now uses an interface to work against which you can implement to get your own feature handler instead modifying the base one and add several special cases code
