Merge pull request #1847 from minrk/inlinecfg...
Merge pull request #1847 from minrk/inlinecfg add InlineBackend to ConsoleApp class list, so it will be included in generated config files / help-all output of the appropriate entry points. This will alleviate some of the annoyance discussed on the list, because the config file will have the whole default rc commented out, so the starting point for user-edits is no change, rather than a blank slate.
