Remove External Storage Handler (#2417) (#2508)

* 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.
