* Updated Grid API
Added Nonull/Nullable/Nonnegative where applicable.
Deprecated unused methods
Changed concrete classes with interfaces (HashMap -> Map)
IGridTickable will no longer accept null as TickingRequest. Do not
implement it, if it should not tick.
* Renamed parameter to match conventions
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.
