separate "extra" tarball

There are a few plugins and extensions, which are not packaged into the
distributed ewiki tarball for size reasons. You can obtain it from your
favourite dealer, or from our downloads/ directory as "extra-CVS-*"

The package currently just contains a minimal spam filter (which after all
isn't very useful for a Wiki site), but in the future will also provide
additional example/ layouts and some image/graphics/icons for layout
beatification purposes.

next >> "Updates + How to deal with tweaked code"

You cannot modify the README.plugins file, but anyhow any ideas or suggestion should as usually get filed on BugReports, UserSuggestions or even better the README.plugins.Discussion.
