fixed music bug for Momir and Random game types. The functions that determined if a file existed did not handle errors properly. Instead it would return an empty string which when appended to the base path would always return true. Thus a non-existent file would always be treated as if it existed. The guards I put in test for empty strings before continuing evaluation. I may have been a little judicious in the places where I put the gaurds in. We can remove the guards if it turns out we don't need them in all the places.
