Object Viewer: (1) Shorten Viewer actions text, (2) New OpenObj basic cascading
Bug Number: NA
Release notes (y/n):  N
For Release Nums: 7.1

The menu action text for recently added operations (prior commmit) for 
managing Open Object Dialogs and the Object Viewer was shortened.

   (1) Workspace Objects menu:

      (a) Open Objects...
      (b) Open Objects Individually...

   (2) Workspace Object Icon context menu:

      (a) Open Objects...
      (b) Open Objects Individually...

   (3) Object Viewer "File" menu:

      (a) Undock Object
      (b) Undock All Objects

   (4) Open Object Cluster dialog "Object" menu:

      (a) Open Objects...

ALSO: When showing an (individual) Open Object Dialog for a particular object
for the first time (in the RiverWare session), it's initial position is 
cascaded.  A simple cascading algoithm for this is implemented in method:
OpenObjectDlg::showEvent(QShowEvent*).
