* Headers/AppKit/AppKit.h: added NSHelpManager.h.

* Headers/AppKit/NSHelpManager.h: declaration for new method -pathForHelpResource:
  * Source/NSHelpManager.m: implemented -pathForHelpResource: in the NSBundle 
  category. -pathForHelpResource: looks for help files giving the priority
  to localized resources. 
  -showHelp: looks for rtfd files too.
  * Source/GSHelpManagerPanel.m: various fixes to avoid a crash when quitting
  and to resize correctly the NSTextView.
