Message 252371 - Python tracker

This patch does two things: 1. restore the Help button and make it display something; 2. lower case the method names.  The latter is a separate issue, best done in a new file.  What is needed for #25313 is tab-specific text.

Also, now that Config Extenstion uses a list rather than tabs, it couldn be added as a tab to the main dialog, and only one set of button event handlers would be needed.  Tab-specific text would be needed first.
