* IC2 rework to avoid a coremod or @Optional
Updated IC2 dependency
Refactored IC2 itemcharging to use an IBackupElectricManager.
Allows charging any ae powered item by using an IBackupElectricManager
instead of having to implement IElectricItem and stripping it by some
sort.
Updated IAEItemPowerStorage to use Actionable for an easier handling
with power APIs supporting a simulation.
Refactored EU P2P to avoid method stripping
Use a modified internal BasicSinkSource instead of implementing
IEnergySource and IEnergySink directly on the tunnel.
Removed the superfluous EU P2P layers.
* Removed internalBattery due to being too complex
* Creative Energy Cell is not a chargeable item
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.
