This integrates our Console object (used by rb-site and manage.py)

into our pre/post-upgrade code. This is used to provide nicer

wrapped/styled output for errors that fits in with the rest of the

upgrade appearance.
There are some issues with the display of the output, but that's an

issue in Console, and will be addressed separately.

Triggered the two SCMTool failure error cases (failure to import, and

conflicts between Tool entries). Saw the formatted output.
