  Seem to have fixed problem with Mac failing to launch when started from Finder.  For some reason, a parameter that begins with '-psn_' followed by a number is passed to the wb_view which does not recognized it and then exits.  Because wb_view is started from the Finder, the error messge is never seen by the user.  http://stackoverflow.com/questions/10242115/os-x-strange-psn-command-line-parameter-when-launched-from-finder

  Moved the OSMesaDummy functions from GuiQt into their own, new module OSMesaDummy.  Having the dummy OSMesa functions in GuiQt did not work for linking on all systems.  As mentioned in a previous commit, the dummy OSMesa functions are needed to prevent OpenGL 'clashes' now the the 'wb_command -show-scene' command is used in Workbench as part of the Help System.
  Fix compilation with ZLIB on John's Mac.
  Additonal changes for Help Dialog: Add help for each 'wb_command' operation.  Use a Tree Widget (hierarchy) for the help topics.  Added deletion of CommandOperationManager to wb_view.  Had to create some 'dummy OSMesa' functions for linking to the GUI.  If the real OSMesa library was linked by the GUI, it totally screwed up the GUIs OpenGL.
