Moved help system code to the HelpSys module. Removed the HelpSystem module.... 

Moved help system code to the HelpSys module. Removed the HelpSystem module. This was done to improve backword compatibility with Zope 2.1.6 and earlier.

Zope's built recently from CVS may have problems with this change. If I hear a lot of complaints I may add backward compatibility, otherwise it should be easy enough fix by either erasing your database or replacing your HelpSys object.
