Add more functionality to colors.ts

[lisaychuang]

Add more functionality to colors.ts, some ideas are:

• X11 colors
• background colors (maybe prepend colors with 'bg'?)
• text formatting styles: bold / italic / underline / strikethrough
• font size: normal / medium / Large?
• shadow (“text-shadow: 1px 1px 1px #000”)
• add borders (“border 1px solid #aaa”)
• add Console.Table
  Logger.table should accept a 2D array, e.g.

 console.table([
    ['hello', 'abc'],
    ['world', 'def']
  ]);

Could also consider supporting these fun libraries:

• console.image
• console.snapshot
• console.meme
