- Change default: IDLE now starts with Python Shell.

- Removed the File Path from the Additional Help Sources scrolled list.

- Add capability to access Additional Help Sources on the web if the
  Help File Path begins with //http or www.  (Otherwise local path is
  validated, as before.)

- Additional Help Sources were not being posted on the Help menu in the
  order entered.  Implement sorting the list by [HelpFiles] 'option'
  number.

- Add Browse button to New Help Source dialog.  Arrange to start in
  Python/Doc if platform is Windows, otherwise start in current directory.

- Put the Additional Help Sources directly on the Help menu instead of in
  an Extra Help cascade menu.  Rearrange the Help menu so the Additional
  Help Sources come last.  Update help.txt appropriately.

- Fix Tk root pop-ups in configSectionNameDialog.py  and configDialog.py
