Reducing Base-64 icons sizes

[cpcnw]

Saved as gif got these a bit smaller - although not transparent i.e. white background

case 'asc': exit(base64_decode('R0lGODlhBwAHAIgAAAAAAAAAACH5BAEAAAEALAAAAAAHAAcAAAIIjI8Ju8eaYiwAOw=='));
case 'desc': exit(base64_decode('R0lGODlhBwAHAIgAAAAAAAAAACH5BAEAAAEALAAAAAAHAAcAAAIKjI9pkODnopqmAAA7'));
case 'directory': exit(base64_decode('R0lGODdhCgAKAIgAAP///wAAACwAAAAACgAKAAACFER+oBrb/gxKq6aJTWUtQmp5ITYVADs='));
case 'file': exit(base64_decode('R0lGODdhCgAKAIgAAP///wAAACwAAAAACgAKAAACFUR+oBps+2JzUTI0J8yQ6sV1GYYABQA7'));
