updated build to include sources inside the .jar, making it easier for others to look at what exactly the plugin is doing (debugging tools will notice the .java files)
Merge branch 'master' of github.com:RobertZenz/org.bonsaimind.bukkitplugins
update Metrics and EventListener to reflect new bukkit onlinePlayers collection change. Also update Metrics to new version so I stop getting noise about that.
added `onEnable` and `onDisable` events. Lots of caveats though, see docs for info (or examples for a taste)
