Modified the "leaveToolSession" and related code to allow the tool to pass the userid (which it gets from UserDTO in the shared session) rather than pass User (which the tool doesn't have). Rejigged the tool jars loaded on the classpath so suit the most "completed" tools.
Updated web.xml to include the context files for all the "current" deployed tools. Added matching tool jars to classpath. Stopped deploying the classes to WEB-INF/classes Implemented more calls on the dummy monitoring page to access the learner pages.
