BackupSaves skips saves when a game has no options files

[zalgebar]

Bug

GameBackupSystem/GameBackups.cs (~line 91):

private void BackupSaves(string baseBackupFolder, bool overwriteFiles)
{
    if (SavesFolders == null || OptionsFiles.Count < 1) return;   // wrong list

BackupSaves returns early when there are no options files, so a game
configured with save folders but no options file never gets its saves backed
up. It also throws a NullReferenceException if OptionsFiles is null (it
null-checks SavesFolders but then dereferences OptionsFiles).

Fix

Guard on the list the method actually uses:

if (SavesFolders == null || SavesFolders.Count < 1) return;

Severity

Data-protection: silent failure to back up saves — the tool's core job.
