Program exits on F5 trying to parse wrong flags

[paoloose]

When restarting with F5, this for loop will try to parse_time all flags other than -p

sowon/main.c

Lines 238 to 253 in eb3a37c

	case SDLK_F5: {
	displayed_time = 0.0f;
	paused = 0;
	for (int i = 1; i < argc; ++i) {
	if (strcmp(argv[i], "-p") == 0) {
	paused = 1;
	} else {
	displayed_time = parse_time(argv[i]);
	}
	}
	if (paused) {
	secc(SDL_SetTextureColorMod(digits, PAUSE_COLOR_R, PAUSE_COLOR_G, PAUSE_COLOR_B));
	} else {
	secc(SDL_SetTextureColorMod(digits, MAIN_COLOR_R, MAIN_COLOR_G, MAIN_COLOR_B));
	}
	} break;

So when running with -e or clock mode and hit F5, the application will close with '-e' is not a number and 'clock' is not a number respectively.

I will make a PR :)
