+ Added custom textures for nukes and category button
+ Added Activation Key
+ Totally updated config file (you'll have to delete the old config.yml)
+ Nukes now don't activates itself, they're placeables!
+ Added command /sfnukes (with arguments reload and version)

* Working on improve performance, so the code is under testing. If you find a bug please report it on discussion.
