* Cleaned up unused Mod integrations other than for mods that are likely to be integrated soon.
* Introduced an easier Facade class to access mod integration abstractions (called Integrations).
* Removed the link between IntegrationType and integration abstraction. Integrations are now explicitly instantiated inside of IntegrationNode.
* Implemented an adapter for IItemHandler so it can be used by the Storage Bus.
* Added update hook for inject/extract to ItemHandlerAdapter.
* Implemented ItemHandler and FluidHandler capabilities for the condenser, as replacement for the Void Inventories.
* Removed external storage handler, added capability-based way of accessing a monitorable ME network via the storage bus. Removed special case inventories for the matter condenser.
* Implemented InventoryAdaptor for IItemHandler. This also now fixes molecular assemblers interaction with part interfaces.
Removes the improper way to set itself into a public static non-final variable.
Removes the direct access to the IntegrationRegistry from AppEng. Will be added at some later point somewhere else for non-singleton access.
Constructor is set to package private to enable possible construction from unit tests. Are current not runnable sind it is currently tied to the FML Loader instance.
