Changes

Minor code formatting

GJULE integration with GlassFish

- own folder and CL for bootstrap dependencies - no need for JVM options
- sorted logging.properties
- HK2 services ARE NOT the logging system, but USE the logging system
- AdminMain sets the log manager, but doesn't set the configuration yet - this
  step is on the server (it has to load logging.properties first). All log
  records are buffered automatically -> no need for earlyLogMessages any more,
  they also contained around 20 selected messages, but all other logs were lost.

- url classloaders have toString
- DirectoryClassLoader doesn't throw IOE but ISE -> if anything would go wrong,
  we have ISE with stacktrace instead of NPE following swallowed IOE.

- Fixed some log messages
- Fixed SecurityManager complaints in QuickLook tests

Fixed printing OSGI issues in EmbeddedOSGiGlassFishRuntime

- originally I even removed the FelixPrettyPrinter usage as I did not see
  any difference, then I noticed that MultiExceptions are sometimes incorrectly
  layered by HK2 and it was possible just to enhance the algorithm for
  finding the BundleException.
- moved and extended the test from main to JUnit.

Level of "service (un)registered" message changed from INFO to CONFIG

- it is not relevant for the user

The systemRootLoggerLevel changed to systemRootLogger.level

- it is a standard
- affects also get-log-attributes output, etc.
