ongoing work on the documentaiton

Moved all html docs in a "pages" directory. They are now filtered to display values of variables like ${project.version}.
The site.css and print.css files have also been moved to allow a more comfortable edition of the html docs.

Minor fixes

This test should now run fine under any time zone

A prepareMessage(Object message): String method has been added to the Category class to check 
whether the message is null or not and to take care of the casting.
The InvokeLog4jTest class has been removed and replaced by a LoggerTest class that tests the same things, plus the
changes related to bug #45. Compared to the old test class, the new class tests all this silently.

JMXConfigurator now returns List<String> types instead of List<Logger> and List<Status> since it does not display information properly when connecting with jConsole.

Updated pages to use the same template scripts
Removed duplicate scripts
