[Jelly] BCEL Taglibrary applied changes

["Mark R. Diggory" <md...@latte.harvard.edu>]

Thaks everyone for all the great ideas. I've applied many of the changes 
suggested in the list. I've also moved the taglibrary into the 
org.apache.commons.jelly.tags.bcel namespace for future inclusion into 
the Jelly taglibraries CVS tree. First however, I want to expand upon 
the Class Extender to attempt to apply some of the ideas that Jouzas 
suggested in relation to BSF.

The new syntax is outlined in the attached model.xml file.
