Add margins.horizontal/vertical helpers that return added up margins along one axis.

Browse Source 
Adding up margins along the horizontal or vertical axis is often
done to calculate sizing or spacing. This tends to result in scary-
long and bug-prone expression being bound to props, since nobody
seems to like to blowing them up into a code block with a separate
variable assignment. This aims to increase the readability of com-
plex expressions by summing axis margins into a single operand.
