* Refactored the BaseActionSource
It now uses an interface `IActionSource` instead of a concrete class and further
subclasses.
Instead of relying on a specific class for a certain action type, it now
uses methods with Optional as return values to determine a player or
machine issuing an action. Refer to the JavaDocs for the exact behaviour.
* `IActionHost` no longer extends `IGridHost`
It never used the additional functionality and if needed the `IGridNode`
will also provide a reference to the corresponding `IGridHost`.
Due to most crafting related GUIs being hardcoded to `IGridHost`,
they no longer work when `IActionHost` is not extending it. Actually
`IActionHost` is the better solution for it, as it prevents us from looking
the grid up via the `IGridHost` and potentially finding a wrong grid.
* Interfaces now only lock the currently worked slot.
This allows `DualityInterface#onChangeInventory` to update slots of the same interface, should they be the source for a requested item and therefore updating their working set accordingly to queue further crafting requests for unfulfilled stack requirements.
* 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.
