First release.

• Works with Pterodactyl 2.0 (eggs and tags) and 1.x (nests); the version is detected automatically.
• Same server settings and product options as Paymenter's built-in Pterodactyl extension, so existing servers switch with one command.
• Egg tag filter on the product page, preselected from the nest a 1.x product used.
• Node reservation tags for automatic deployment on Pterodactyl 2.0.
• Lists that span several pages (more than 100 nodes, locations or eggs) are read completely.
• Clearer error messages with the HTTP status and the panel's reason.
• Fixed: a port array without SERVER_PORT now gives a clear error instead of a PHP warning.
