Title: Addgrader.sh can now be run more universally

If you have a signing key and it's already in the repository, it will not do anything.
If you have a signing key and it's not in the repository, it will add the key to the repository.
If you don't have a signing key, it will generate a new key as it did before.

Keys existing in the repository will no longer get overwritten.
