Beta 4 released

[Daniel Leuck]

Hi Folks,

Beta 4 has been released:
http://sdl.ikayzo.org/docs/display/SDL/Downloads

This is a minor update.  Changes:
- suppressed warnings in appropriate areas
- added serial version ID
- updated JavaDoc

I am thinking of writing a Ruby port.  There seems to be a lot of activity
around the Ruby on Rails project.  Hopefully Todd will get around to a C++
port :-)  The primary languages I would like to support within the next six
months are:

Done:
- Java
- C#

TODO:
- C++
- Ruby
- Python

If any of you have projects requiring SDL in another language, please let me
know.

Cheers,
Dan
