Metasequoia modeler tutorials and Keynote translated plugins

[HwitVlf]

Added one more translated plugin (batch #4) to top post, and new link to a good Metasequoia function tutorial.

The plugin lets you draw new polygons on an existing polygon.- good for making filigree designs on parts or many other creative endeavors. Basically, it works like the 'create' function, but it sets new vertices aligned with an existing face so it's much easier to control. ‎  It makes a new 'poly-surface' button in the 'command' menu
