Added addional logging to the ClassChecker#hasMethod method in order to
better diagnose why a test fails. In order to see the diagnostic messages,
you need to activate logging with level of "FINE" for the web module under
test.
Since much of the TCK work is done on Pluto, added logging.properties files
to each of the web modules ot activate logging. The log level is set to:
javax.portlet.tck.level = FINEST
and the logs are all written to the javax.portlet-tck.XXX.log file.
Moved the signature tests to separate modules and implemented more of them.
Completed code generation for signature verification mdules
Implemented FilterChaing and FilterConfig signature tests.
Added a pluto.css file to the output files in the deploy-files directory.
This CSS file sets the navigation bar on the left side and provides a more
compact format for displaying the test cases.

Use of this pluto.css file is NOT required in order to run the tck. It is
provided as a convenience for Pluto users.

In order to use the more compact layout, copy the pluto.css file from the
tck deploy/target/deploy-files directory to the Pluto webapps/pluto
directory. This will overwrite the existing pluto.css file in that location.
