Allow AUT to cascade updates into a single operation

Problem:
When AUT does an update it only takes one file from the document to apply/install that update. That means that FixPacks and Language packs do not get applied in the same update/install transaction from AUT.

Proposed Solution:
Allow multiple files to be attached to the AUT document that can be used to update in one go the Notes client.

• Notes 12.0.2

• Notes 12.0.2 FixPack 2

• Notes 12.0.2 Language Pack

When this AUT task executes it would install all three files to get the client up to the latest level in one exercise.

Acceptance Criteria:
As an Administrator I can cascade files in a single AUT document.

As a User the client does all the installs required in a single operation.
