* Visualizations visible to Analyzer can be enabled or disabled by changing the file "package-res/resources/web/analyzer_plugin.config.json". Changes affect next opened window of the Analyzer editor/viewer.
* Because the first Visualization of each type can be disabled, which visualization has the "menuSeparator: true" setting is now dynamic and handled automatically upon viz registration.
  Menu order is: 1) by viz. type, alphabetically (not visible to the user) and 2) by viz. name, alphabetically.
* Added known AMD module loader plugins: "json" and "text"; just slightly adapted to use pen.define and pen.require.
