implement Stalker Anomaly local saves

[Y3sMan]

The Stalker Anomaly saves' directory is described in "fsgame.ltx," located in the game-root directory, and writes to, normally, "appdata" in the same directory. This attempt at local saves, upon game launch, renames the "appdata" folder to "mo__appdata," then links the current MO profile's saves directory into the game directory. If there are any changes that need to be made, let me know.
