fixup
ignoring Plugin means you can't run the script ON plugins

That's not the idea
read dry run from task parameters
don't just correct app usage

otherwise the source is just a different fatal error
don't rename $collection vars

otherwise the method body is out of whack
be much more complete with App::uses replacements

Make sure that all use statements that can be determined are taken care
of automatically.
Comment but mark with TODO any unrecognised App::uses calls
furter additions to the implicit class list
