Title: Added support for colorized values

When I wanted to colorize some values, I used the following formatter

```ruby
class ColorFormatter
def initialize(color)
@color = color
end
def format(data)
HighLine.color(data.to_s, @color)
end
end
```

The cells were then padded incorrectly, because the unprintable escape sequence that sets the color was counted in the length of the value. this patch is stripping the unprintable stuff during padding.
