Key locations in Ultima VIII

Like its predecessors, there are many keys in Ultima VIII. It is very difficult to keep inventory, but thankfully a keyring is available very early and thus makes it easy to keep all keys. In order to not confuse the keys, here a complete overview, complete with notes about special properties of said keys.
