Provisional modifications for activating class scanning through the
annotation detector as an alternative to the CDI class scanning for
identifying method annotations. The scanner implmented in
MethodAnnotationRecognizer works. This commit is provisional in nature, and
requires special handling to use.

1) you will need to compile pluto-container with the mvn install -DskipTests
option, since the tests have not been updated to work without the CDI
extension.
2) you will need to copy the annotation-detector-3.0.5.jar file into the
common tomcat lib directory.
3) you will need to move the weld jar from the common tomcat directory into
each of the portlet WEB-INF/lib directories for the portlets that use CDI.

Note that the CDI portlets won't work due to class loading issues with the
CDI extension.
