Changed the owner and dialogue of the secret store

The owner of the secret store has been changed to Anna, and the messages in the store has been changed accordingly.

Of course, this change is really just a hobby, as the function of the store remains the same. There were a lot of things to change, and it was a lot of work, but I knew this absolutely had to be done. Because it is no fun to go all the way to a secret store and have the usual old man say, "This is a tool shop".
