py-cvs-rel2_1 (Rev 1.33 - 1.37) merge

VP IDLE version depended on VP's ExecBinding.py and spawn.py to get the
path to the Windows Doc directory (relative to python.exe). Removed this
conflicting code in favor of py-cvs updates which on Windows use a hard
coded path relative to the location of this module. py-cvs updates include
support for webbrowser.py.  Module still has BrowserControl.py for 1.5.2
support.

At this point, the differences wrt py-cvs relate to menu functionality.
