Announcing Pyke 1.0.4 Release

The big changes for Pyke are:

1. The project was moved from subversion to mercurial to make it easier to contribute. (This was actually done in the 1.0.3 release that was never announced).

2. The release packaging was redone to simplify things. There is only one zip file now that contains everything, including the HTML documentation and the examples.

3. There is now also a release package for a version of Pyke that runs on Python 3.

4. There is a new "About Pyke" => "Modifying Pyke" web page to help those that would like to make changes or enhancements to Pyke.

Plus many other smaller changes.
