Improve performance by 10000%

Quite frankly, the performance of this plugin was crap.  This patch removes all the HashMaps and improves performance by 2000%.  OnPlayerMove used to take 6ms before this patch and was using 50% of all CPU cycles on the server (yes, that is correct 50%).  After the patch, onPlayerMove now takes 0.3ms and ~0.3% of all CPU cycles.  Patch also includes mavenization of your project and renames the plugin from "Advanced AFK" to "AdvancedAFK" (which is mostly needed for plugin reloading via PlugMan).  The rename means you will have to rename the config folder.
