Add div around headline & body text (excluding image)

[ashyablok]

Currently, pathfora does not have a wrapper div around the headline text and the main content of the modal, that does not include the image. To allow for proper image floats (without setting a width on the image) we'd want a div that could be flexible:

For example:

This looks ok, but when we try to do this with a smaller content space the image is constrained to just the text and button space, and with a width set, it looks odd.

@sarahyablok should we add this for both modals and slideouts?

@kristinh12 I would guess all module types.
