Support for noresume kernel option

[grisxa]

Hello!
Sometimes I need to specify "noresume" kernel option to avoid resuming from swap partition specified earlier. When I boot from CD I can't just remove "resume=" parameter from isolinux.cfg (don't ask me why it is there ).
So I've found useful if tc-config could ignore "resume" option in case "noresume" is specified too. See my patch.

Looks good to me.
