Adventure map, when a sign has not yet been visited (and a bottle, and a Sphinx), indicate whether there is a message written on the sign, or whether there is no message written on the sign

[LeHerosInconnu]

In fheroes2, it would be nice that when the player right-clicks on a not yet visited sign, to indicate whether there is a message written on the sign, or whether there is no message written on the sign (when the sign has been used purely decoratively by the scenario creator).

Sign with a message, display:
"Sign

(message)"

Sign without a message, display:
"Sign

(no message)"

In fheroes2:

Same thing for the Bottle on the ocean.

Bottle with a message, display:
"Bottle

(message)"

Bottle without a message, display:
"Bottle

(no message)"

In fheroes2:

Sphinx with a riddle, display:
"Sphinx

(riddle)"

Sphinx without a riddle, display:
"Sphinx

(no riddle)"
