ADOM should handle old saved games more gracefully
The game crashes if a saved game in an older format is found
ADOM should ignore saved games in an older format (or maybe move them to another folder). Right now it crashes with the following error message (which is not shown on Windows / OSX):
/*
* ADOM session aborted due to an external problem.
* Problem Description: Required save file version for this game: "1.2.0"
Actual save file version: 1.1.1 Gamma 0
