Moved all private methods into seperate category. New method
[_connectApplication:], use this in [openFile:...] and [launchApplication:...]. Implemented [openTempFile:]. New method [_workspaceApplication] used to implement [performFileOperation:...] and [selectFile:inFileViewerRootedAtPath:]. git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/gui/trunk@11591 72102866-910b-0410-8b05-ffd578937521
