Visitor notification

[miloshykk]

Hello, I think that adding an option to notify players when someone visits their island would be an interesting new development that I'm sure many people are missing.
Something like: Player X has visited your island.
And maybe some kind of notification when we visit someone else's island, like: Player X has visited your island:
You have visited player X's island.

All the best to you, I hope the proposal will be introduced!
