Subject: [PATCH] vanitygaps - adds gaps to layouts

This patch differentiates between inner and outer gaps as well as
horizontal and vertical gaps.

The logic of these layouts also aims to be pixel perfect by ensuring
an even split of the available space and re-distributing the remainder
among the available clients.
