[Unknown Mod][Game] Create an automatic incremental save file at the beginning of each turn

[LeHerosInconnu]

Create an automatic incremental save file at the beginning of each turn.

The file name consists of the scenario name and the day number.
For example, with the “Broken Alliance” scenario on day “4”:
“Broken_Alliance_0004”
The file is generated only in single player mode.

This is an option.
“game: create an automatic incremental save file at the beginning of each turn“
This can be implemented directly in fheroes2.
