Plugin - Fixed missing console output in CB v1.7.2

With Craftbukkit 1.7.2 they changed logging behaviour so that not all messages that are printed to the console are saved in the logfile. Thus, if you type 'help' the response would not be sent to the Remote GUI. Hooking into the log4j RootLogger fixes the problem.

Therefore I replaced the LogHandler by an appropriate LogAppender and adjusted your main class. For compiling you need either craftbukkit or log4j in your buildpath.
