Rename LogUtil to StaticLog.
Move StaticLogFile to NCPCommons, make use of the useBukkitLogger flag.
[PLACEBO] Raw sketch of the upcoming logging framework, doing nothing.
[BLEEDING] Use the new logging framework from now on (read details).

* All logging is also going into the log file (always), debug output is
mostly/only going into the log file. File logging uses an asynchronously
processed queue now (!).
* Specify an existing directory (e.g. logs) and log files will named
after date + sequence number, changing with every reloading of the
configuration.
* Console and ingame logging remain within the primary thread.
* No extra configurability for customization, yet.
* Not all places have been cleaned up, concerning log levels. target
streams and package naming.
* Work in progress.
