Feature: padding-y (vertical padding, top bottom padding)

[phisch]

I was a bit surprised to see that we can only set padding-x in the configuration, and was wondering if it was possible to add support for vertical padding (top and bottom) as well in the future?

Hey there, sorry for the delay on reply. Implemented padding-y (top and bottom) on main branch, will be released on 0.1.4.
