Removed: Support for NMS below 1_5_R1

This removes NMS support for anything below 1.5. Those version probably can't really run RoyalCommands with much success anyway. When I need to add a NMS function, I have to add it to /every/ version of NMS I support, so this makes that easier for me, as well.
Updated: Config refactor!

This update has completely redesigned the config.yml file. It now uses groups. This is not a final version of the configuration file, but it's a start. If you notice anything odd, please, please let me know. I have double-checked this, but it may not be perfect. If a value belongs in another group, or if a config value isn't changing anything (that means I didn't update it in the Config.java file), tell me. Basically, if you have any thoughts about this update, tell me.
Fixed: Various config paths around the plugin
Fixed: Remove support for NMS before the refactor
Updated: Formatting fixes
Added: Spawned item tracking!

This adds a system for tracking spawned items. It currently only affects /i and /give. If it should affect something else, let me know. You can check information on spawned items with /spawninfo. This will track through block place/breaks, crafting, and smelting (untested). Give me any feedback you may have!
