Many exceptions got an improvement due to changed class or description or details it is providing.
Is not complete, needs to be done in patches in the regions, where it is needed, since some are just
swallowed.
Removed total usage of pure RuntimeExceptions to 0.
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.
The new update contained a split of the IEnergyHandler into the IEnergyReceiver and IEnergyProvider.
Since all tiles in AE2 are basically IEnergyReceivers we use them and changed the detection of opposing tile entities from IEnergyHandler to IEnergyReceiver
