Refactored the BaseActionSource (#3063)

* 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.
