New box styling options for more spacing controls

We’ve added two more box styling options:

1. The first option at the top allows the box to stretch full width (within its container) versus the default behavior (when this option is unchecked) that wraps the content inside the boxes.

2. A new vertical spacing (margin) option was added that allows you to change the box spacing (and the labels) before and after its placement. Currently, a custom CSS is to be written in your theme to tweak the spacing. With this new option, you can do this without any code change.
