Opens applications, documents, and folders. Applications are opened via an 'oapp' or 'rapp' event. Documents are opened in their user-overridden or default applications as appropriate. Folders are opened in the Finder.

Returns a folderitem to the application which was launched.
Currently this function is not available to RB versions before 3.5.
Note that the documents parameter is an array of folderitem and not just one.

Upgraded in version 19.5 to use CFURL instead of FSRef APIs.
