Some useful skripts, will be added to.

HTTP.sk - Allows you to receive http requests from external sources.
Dialog.sk - Allows you to use dialogs. You must be on server version 1.21.10. Other ones will not work due to API changes. Example script: https://pastebin.com/PYKyr0vy
Mannequin.sk - Allows you to use mannequins as skript doesn't have support for them yet. Gson.sk - Allows you to quickly convert list variables into json and back. Feel free to make an issue if you have suggestions or find a bug.
