Version 2.4

After a longer delay, we have some more minor changes and fixes:

• Error in String ALLOWED_CHARS fixed
• Use SimonUtils.presentNanoTime in jmx StopwatchMXBean (added methods)
• Make "register" protected in JmxRegisterCallback
• experimental JDBC4 driver was added to existing JDBC proxy driver (was for JDBC v3)

Nothing big, but at least some of us are still alive!
