Get rid of usages of Guice in the FitNesse tests.  Added support for configuring the JMX URL used by the MBean fixtures.  This isn't working all of the way yet because of problems accessing JNDI.  It want to commit this as a checkpoint, though.
Extracted the test web application from the fitnesse project into its own project in hopes of working around classpath issues with JNDI look inside fitnesse.
Moved the SystemPropertiesMBean class into the "common" project so that it can be shared between the test-webapp and fitnesse.
Finally got the SystemPropertyMBean fitnesse tests working.  Well, almost.  I had to comment out some tests that passed in wiki mode, but failed when with run-tests.  I don't understand what's different about the two environments.
