Leo 4.2.1 final released

[Edward K. Ream]

Leo 4.2.1 Final is now available at http://sourceforge.net/projects/leo/

Version 4.2.1 corrects problems associated with Python 2.4:

- Leo's Pretty Print command was broken by the new use of '@' in Python 2.4.
- Leo's installer was broken by the new installer used in Python 2.4.

This will likely be the last 4.2.x release of Leo. Leo 4.3 alpha 1
will be released shortly. In spite of its name, 4.3 alpha 1 should be
solid enough for most people.

Besides version numbers and readme files, there have been no changes made
between 4.2.1 beta 1 and 4.2.1 final.

Highlights of version 4.2:
-------------------------
- @thin trees make Leo much more friendly to cvs.
- Leo's data structures have been reorganized to make outline
  operations significantly faster. All old scripts still work.
- @test and @script nodes convert scripts to unit tests automatically.
  You can convert scripts to unit tests in seconds!
- A faster and more robust spell checker plugin. (requires Python 2.3)
- Leo is now much more friendly to using spaces instead of tabs.
- The Execute Script command reports erroneous lines more clearly.
- Leo draws large outlines more quickly using less memory.
- Dozens of other improvements.
