Merge styles into callouts (inky)

[garygreen]

At the moment you can only have a defined padding, etc as per the settings in inky. It would be nice if internally it would merge some of the styles so you can override them for a certain callout.

I'm sure this would apply to most other components as well.

<callout>
    $callout-padding defines this to be 20px
</callout>

Would be nice:

<callout style="padding: 30px;">
   $callout-padding is essentially replaced with custom 30px.
</callout>

Are you looking for a way to control the padding inline? How would this improve over using an existing SCSS setting?
