M configHelpSourceEdit.py 1. Attach configHelpSourceEdit error dialogs to parent to avoid Tk root pop-ups. 2. Make configHelpSourceEdit OK button the default and bind <Return>. 3. Reformat configHelpSourceEdit. 4. ConfigDialog.SaveAllChangedConfig() had a bug which caused additional help sources to be deleted when other config items were changed. 4. Uniform capitalization in configDialog. 5. Update configDialog doc string.
