version 1.3 released

I have made version 1.3 available in the file section. (it is not in the cvs, for i have some problems to synchronize it with my private cvs). it includes representation in UTF8 and UTF32. It should work with SmallEiffel, Visual Eiffel, and ISE Eiffel. Unfortunately, it currently does not contain documentation, but this will be solved in a week. The unicode database was speeded up -- i am using large (but compressed) integer tables instead the hashtables of the previous versions; so the start up is quicker.
