The command-line argument parsing code has a lot of copy-paste. This copy-paste would get even worse if I added safety checks to make sure you couldn't index argv out-of-bounds by having an argument like `-renderer` without having anything after it, i.e. you'd be doing the command `./VVVVVV -renderer`. Previously, only the playtest arguments (apart from the recently-added `playassets`) had this safety check, but the message it printed whenever the safety check failed was always "-playing option requires one argument" regardless of whatever argument actually failed to be parsed. So I fixed it so that all arguments actually output the correct corresponding failed argument instead. Also, `strcmp(argv[i], <name>) == 0` is really kind of noisy, even if you understand what it does perfectly well. So I refactored it with a bunch of macros. ARG() just does the strcmp() char* comparison, and ARG_INNER() does the safety check and returns 1, along with printing a message, if the safety check fails.
