repos/blastem: stateview.c annotate

annotate stateview.c @ 792:724bbec47f86

Use a new fatal_error function instead of calling fprintf and exit for fatal errors. This new function more gracefully handles the case in which BlastEm was not started from a terminal or disconnected from ther terminal (Windows).
