Add pending actions for new inventories

When a new Inventory is added to GG-CE, the system must automatically register two PENDING InventoryAction records:

1. QUANTITYSET: Quantity update -- The actual amount of material is inspected.
2. LOCATIONSET: Location update -- The location of the inventory is set.

These two actions are automatically closed when:

1. QUANTITYSET is closed when Inventory#quantity is updated
2. LOCATIONSET is closed when Inventory#storageLocation1..4 is updated

The codes need to be registered as CommunityCodeValues.

It may be sensible to add an aspect on the #save method(s) of InventoryRepository, check if Inventory is not yet persisted and add these actions in the aspect.

Also the InventoryService#addInventoryAction should first try to close an existing pending action before adding a new one. It should be renamed to #closeInventoryAction.
