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.
Reworked whole Version Checker with an extensible interface to add any other service later on easier.
The version checker now has its own config file, to collect the different options and extract them from the main config file.
In that you can specify how fine the versions should be checked.
The AE2 has in the contract that the item field in an IAEItemDefinition can be null due to the fact, if a special item is deactivated. This needs to be checked.
The base code was enhanced through Javadoc and split in responsibilities
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
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
