Support DVD-wide aggregation/listing of all files in all CABs on from a DVD

From https://code.google.com/p/lessmsi/issues/detail?id=9

> If I run a setup.exe wrapper on a DVD it presents all the content on the
> disk as one unified feature tree - yet on the disk itself there may be many
> MSIs that comprise this view. The Windows 7 SDK is exactly this way.
>
> So when I know I need a single file out of the SDK, it would be great to
> see all files on the DVD in one view.
>
> What steps will demonstrate the feature request?
> 1. Download the Windows 7 SDK from here:
> http://www.microsoft.com/downloads/details.aspx?FamilyID=71deb800-c591-4f97-a900-bea146e4fae1&displaylang=en
> 2. Examine the package structure - the root install EXE is called
> setup.exe, but it spans everything on the disk.
> 3. Under the "setup" folder there are many subfolders each containing an
> MSI with an external Cab.
>
> It would be great if I could tell lessmsi to open all MSIs in a folder tree
> and present one consolidated view of the files. Would probably be
> necessary to have a column for "MSI" file.

> This is related to issue 7 (http://code.google.com/p/lessmsi/issues/detail?id=7) since it assumes support for external CABs. I agree with the idea and will accept it but it is a relatively big effort so I can't commit to doing it soon.
