Added command line logging configuration which enables log file:

* Size limiting (--log-limit <size in bytes>)
* Rotation (--log-count <count of files>)
* Custom naming (--log-pattern <filename pattern>)
* Append (--log-append <true|false>)
Note: This is done via command line and not bukkit-settings as that would require lots of refactoring of both core server and CraftBukkit due to the current initialisation ordering and depenencies.
All settings default to that of the standard server
