New Revision: 543772

URL: http://svn.apache.org/viewvc?view=rev&rev=543772
Log:
[PLUTO-375], [PLUTO-376]: Pluto 1.2.x now works Tomcat 6.0.x (tested with Tomcat 6.0.13).
 The pluto maven plugin was updated to support installation into Tomcat 6, and the JSP 2.1
Expression Evaluator was implemented thanks to a patch from Benjamin Gould.
