New template engine & preparations for requires online commands.
New: - Base for "require online" feature -> A player needs to be online, before their command runs. This will be implemented in the panel, within the next days.
- New command for the Bukkit version: /cs key <yourkey> -> This will change the key in the config, and restart the donation check task. No need to restart the server after updating the key anymore.
- The webshops are now running on our completely new template system, based on the Twig template engine. Silver members (3USD/month plan)+ can now edit the HTML/CSS of their store.
- We added some of default color schemes, and themes by bootswatch (bootstrap).
Fixes: - The BungeeCord scheduler did not function, because of a missing argument. This has been resolved.
