Allows you to load and unload plug-ins that add functionality to Alias.
Documentation for specific plug-ins is provided as text files, located in ODS/OpenAlias/plugins/ under the specific category of plug-ins (DataTransfer, Gifts, Miscellaneous, Modeling, Paint, or Rendering) in the help subdirectory. By organizing the plug-ins into separate subdirectories, the plug-ins are similarly organized in the Plug-in manager.
