Improve control over Module Download & Install Process

I would be great if one can set Install to Download/Install/Download & Install/Rollback modes
Maintain + display the status of each queued module.
Keep a backup so can rollback.

From Install queue, then select which queued module(s) to actually apply/rollback.

This will allow one to fetch the updates, but control the update process per module.
(I've found for instance that updating Panels and then Views works much more reliably than doing both at the same time.)

Thank You for this great module.
