[Feature Request] Support removal of specific components from existing backups

[brainchild0]

Problem

Presently the interface supports all of the following:

1. Deletion of backups corresponding to applications no longer installed.

2. Bulk and individual deletion of backups for specific applications.

3. Selection of components to include in new backups

Not currently supported, as it appears to me, is deletion of specific components from existing backups.

Proposed Solution

Proposed are the following three related enhancements:

1. In the per-application view, add an action button for removal of specific components from an existing backup. A pop-up dialogue box would provide the selection of which components to remove.

2. In the action menu for bulk operations, on a selection of multiple applications, add an item for a bulk operation analogous to the action button added to the per-application view.

3. In the Tools view of for global settings, add an operation for removal, from all existing backups, of all components not among those selected, in the global settings, for inclusion in new backups.
