VoidSW: Graceful exit error is missing

On DOS SW if you lack proper tags for i.e. drivable Sector Object, you will get a more graceful exit with the error Forgot to tag outer loop for Sector Object #5

Easy way to recreate this is to open example.map - Navigate to E-F and deleting the ST1 marked 541,0,2 (Bottom right one)

VoidSW Crashes to desktop silently with no error in the logfiles (even on debug). Expected outcome: Exit with an error, i.e. dialogue box
