Issue: XF2.x: Area tree list outer padding could be reduced to align better with directory lists

Currently, area trees have outer padding which seems unnecessary. This is particularly noticeable in areas where page lists are presented in a 'directory list', as the areas and pages are out of alignment with each other.

As-is, the area tree is functional, so I don't consider this a bug. Though I am all for consistency with core-XF UI (where appropriate) .

At least for sub-areas, vw-area-bit's container element has the class vw-block-content, and removing this class from the container element improves the appearance, in my opinion. I'll attach one original and one edited screenshot which should better describe the styling change that I am suggesting.
