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.
Added zinc to the array of checked ore dictionary names, so if any mod decides to add Zinc in the future or uses it via the OreDictionary, it will be automatically added to the grindstone.
The commit also contains some scoping and code cleanup of the underlaying calls
