colors.js Support light colors

I could find support for light colors so unless i'm mistaken, that would be a nice addition.

console.log '\u001b[33m yellow \u001b[39m'
console.log '\u001b[1;33m ligth yellow \u001b[39m'

Note sure how you would prefer this to be implemented: creating addition colors like colors.lyellow or using colors.light just as colors.dim (cleaner but probably much harder to write). Let me know if you are insterested and i'll take care of it.

+1 to this.

_Caveat: following feedback is Mac-based_ Also, for what it's worth @wdavidw, I would think a bright modifier would be the way to go. For example: .yellow.bright or simply .yellowBright mainly because "bright" is the word that is used in the "ANSI Colors" section of Terminal's Settings. I'm thinking about making a pull request for this, but you mentioned that you had wanted to take care of it, so let me know if I can help :)

Furthermore, it might be worth mentioning in the README that the user can sort-of bypass the need for the bright modifier by using the "Use bright colors for bold text" Terminal setting. However, with the current repo, this only covers text color and not background color.
