Changes to miniLogger 1.0

Changes are kept in reverse chronological order.

TODO: generalize setSink to allow plugins to other logger with more feature and bigger size (log4j, JDK 1.4, etc.)

added caught() method to Logger that can be used to trace how exceptions are caught - prints "CAUGHT" and exception stack trace on FINER level
changed caught() and throwing() methods to return Throwable argument so it is possible now to log and throw exception in one line: throw Logger.throwing(new MyException());
modified build.xml to generate MANIFEST.MF with version info

added printing of logger name in output (to simplify grep like filtering) and made it intelligent so when name of logger is FQN just [print package name and avoid printing class name as it is printed next as java source file name ...

added global method setShowTime() and changed logger to print by defult timestamps formatted as HH:mm:ss.mmm (more details in RFE) and added property showtime (-Dshowtime) that can control showing of timestamps in log (by default it is set to true)
changed implementation of Logger.setCmdLogger() so that list of anchoredLoggers (this list keeps loggers that are prevented from garbage collecting even when class using them is out of scope) will have no duplicates that otherwise would be created if setCmdLogger() was called multiple times with the same argument
fixed potential bug in Logger.setCmdLogger() when called again with the same argument it created new logger replacing existing one even if there was no need to do it (now it is smart to check for existing logger and only set its level if needed)
changed static initializer of Logger to print exception to System.err about access denied to read system property (java.security.AccessControlException: access denied (java.util.PropertyPermission debug read)) only when Loggers is compiled with static flag WARN set to true
wrapped calls to System.getProperty() for "log" and "debug" into AccessController.doPrivileged() with catching AccessControlException to allow running logger even if system properties can not be accessed

added Logger.entering(..), exiting() and thrown() convenience methods; both compatible with JDK 1.4 and are as well using MINILOGGER ability to automatically get class and method name allowing to write simply logger.entering() instead of logger.entering("FooClass", "methodBar") - this way it is less error prone!
added log methods that takes Object parameter and list of Objects that are converted toString() and printed

fixed bug with weak references: when loggers were configured from command line the reference to loggers were not preserved. therefore when those loggers were garbage collected they disappeared from LogManager and it was affecting setup of default logging levels for new loggers (interestingly showed only under Linux JDK 1.3 and not Solaris ...)
