[Custom] Door Slammer | Deal with uninvited guests the fun way!

This plugin changes doors to push people away when it's closed.
This resource is part of my custom series. You can view the full list here, prefixed by [Custom]. This series comprises of custom requests from server owners, where I help them out for free and in exchange, I keep all rights to the resource. I am releasing them here for any other server owners who can find a use for them.
