Corn manifest

cornstone uses a special modpack manifest called the Corn manifest. The Corn manifest, saved under the file name manifest.json, is a superset of the well-known Curse manifest used by all major launchers like the Twitch Launcher. Being a superset means that the Corn manifest is completely backwards-compatible with the Curse manifest. You can use Curse modpacks with cornstone, and you can use Corn modpacks in Twitch Launcher. The only difference is the addition of some very helpful fields, prefixed with an underscore, which are only understood by cornstone. The differences are illustrated below:

NOTE: The _metadata field is auto-generated and only used for the developer's convenience. You should not edit it. Use the format command to generate or update it.
