Split dependency logic on the BuildCraft modules.
Config needs to be reset, if BuildCraft was disabled actively,
because now there are 3 BC modules to be taken account of
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.
