Correcting level arguments while initializing game (platform/win).

According to some testing:

strstr(argv[1], "--")
0x015f5f83 "--01-Caves.PHD"

strstr(argv[1], "--") == argv[1]
true

argc > 1 && strstr(argv[1], "--") == argv[1]
true

the original game doesn't have such file names

I was able to overload the command line argument and load a custom level, I found somewhere. Everything runs nicely, however I had to change the boolean operator to == in order to load the custom level as such.
